                                 SETTING OPTIONS

          Beam Cookbook lets you view and change various default settings.
          You can change these settings temporarily or store them with the
          program so they're  used from now  on. The  stored, or  updated,
          settings remain in effect until you change them again.

          One option not discussed in this chapter is Screen; see "Setting
          the screen size" on page 18.

            
          THE OPTIONS MENU

          The Options  menu contains  commands that  lead to  other  menus
          where options can be selected.

                             +------------------------+
                             |  Hardware              |
                             |  Screen:      25 lines |
                             |  Preferences           |
                             |  StartUp               |
                             +------------------------+
                             |  Save Options          |
                             +------------------------+


          Caution: F10|Options|Save Options also saves the file  directory
          that is defined in F10|File|Change Directory.

              * Hardware lets you specify or change settings for your com-
                puter graphics card, printer, and the  output device used
                for your printer connection.

              * Screen lets  you specify  whether Beam  Cookbook displays
                text in 25 lines or 43/50 lines.  See "Setting the  screen
                size" on page 18.

              * Preferences lets you  change Beam  Cookbook to  suit your
                needs.  The  options are  divided into  two sections,  one
                that affects Beam Cookbook when you  are using it and  the
                other  saves information when you leave Beam Cookbook.

              * StartUp lets you  specify whether Beam  Cookbook will use
                expanded memory to speed up window display and printing.

          Graphics card options

          Beam Cookbook automatically detects  one of the following  types
          of graphic cards and loads a special file, called a driver file,
          that contains information about your graphics card:

                         AT&T 400 Line       IBM 3270 PC
                         CGA                 IBM 8514/A
                         EGA                 MCGA
                         monochrome EGA      VGA
                         Hercules

          Normally, you don't have to change graphics card options because
          Beam Cookbook automatically chooses  the best configuration  for
          your system.  If your using a nonstandard screen type,  however,
          you might need  to specify information  about the graphics  card
          with F10|Options|Hardware|Graphics.

              * Note: The IBM  8514/A defaults to  the VGA emulated mode.
                You must change  the setting yourself  using the  commands
                described below.

          Choose F10|Options|Hardware|Graphics: to display  Graphics card
          menu.

          BEAMCKBK.CFG.

          At startup,  Beam  Cookbook  searches  in  the  directory  where
          BEAMCKBK.EXE was loaded; if it can't fine this file, Beam  Cook-
          book will use it's own internal  defaults.  If this file  cannot
          be found Beam Cookbook will automatically create it.

                               WORKING WITH BEAM FILES

          Beam Cookbook stores the information you enter in a beam problem
          in system memory, called RAM  (random access memory).   However,
          RAM is temporary.  When you  turn off the computer or exit  Beam
          Cookbook, or there is a power outage, all data stored in RAM  is
          erased.

          In order to use a beam problem  again at a later time, you  must
          save it on either a floppy or hard disk.  Each beam problem  you
          save is stored in a file with a unique name.  Once you've  saved
          a beam file, you can access it  at any time by loading it  using
          the "Open" command.

          This chapter described how to

              * load a beam file

              * save a beam file

              * change the  default directory where Beam  Cookbook stores
                beam files.

              * create a  beam problem  template, that you  can use  as a
                foundation for creating new beam problems.

            
          THE FILE MENU

          You can access  all file  functions with  the F10|File  command,
          which brings up a menu with the following commands:

                                +------------------+
                                | Open          F3 |
                                | New              |
                                | Save          F2 |
                                | Save As          |
                                +------------------+
                                | Change Directory |
                                | Get System Info  |
                                +------------------+
                                |Exit        Alt-X |
                                +------------------+

              * Open  opens an existing  beam file.  If  your current beam
                problem contains data that  you haven't saved, Beam  Cook-
                book asks if you want to save the file first.

          ________________________________________________________________

              * New opens a new beam file.   If your current beam  problem
                contains data that you  haven't saved, Beam Cookbook  asks
                if you want to save the file first.

              * Save lets you save the current beam file, using the exist-
                ing file name.

              * Save As saves the current beam file under a different file
                name.

              * Change Directory lets you change the default directory.

              * Get System Info display information about your system.

                Exit removes Beam Cookbook from memory and returns you to
              * 
                DOS.  If your beam problem contains data that you  haven't
                saved, Beam Cookbook  asks if you  want to  save the  file
                first.

          This chapter covers all File menu commands except for two.  Exit
          is discussed on page 19. Get System Info is discussed on page 21.

            
          ACCESSING FILES

          Once you have saved beam problem data in a file, you can  redis-
          play it at any time by loading it into memory and displaying the
          data by using the input windows.

          The first two commands on the File menu let you load a file:

                * Open loads the file you specify.

                * New opens a new beam file.

          F3 is the shortcut for the F10|File|Open command.

          The following sections describe how these two options work.

          Opening a file

          The F10|File|Open command displays a simple input box for you to
          enter a file name or use DOS-style  mask to get a list of  files
          to choose from.  Here is what the input box looks like.







                                         59




                                 BEAM COOKBOOK 1.0
          ________________________________________________________________

               +-------------------- Open File ---------------------+
               |                                                    |
               +----------------------------------------------------+
               | OK                                                 |
               +----------------------------------------------------+

          The input box opens with the default mask '*.BCB'.  Now you  can
          do any of these actions:

              * Press Enter and display a list of beam files  in the cu r-
                rent directory.

              * Type in a full file name  This will load the file.

              * Type in a  file name with wildcards. This will display  a
                file list.

          The input box lets you enter  a file name explicitly or enter  a
          file name with standard  DOS wildcards (* and ?)  to filter the
          names displayed if the file list  box.  If you enter the  entire
          name and press  Enter or click  on OK, Beam  Cookbook opens  it.
          (If you enter a file name that Beam Cookbook can't find an error
          message is displayed .)  You  can include the path if  different
          than the default directory.  If   leave off the file  extension
          Beam Cookbook will use '.BCB'.

          Using the File list box

          The File list box displays all file names in the current  direc-
          tory (unless you specified a  different directory in your  wild-
          card) that match  the specifications in  the input box,  display
          all drives,   displays the  parent directory, and  displays all
          subdirectories.  Here is what the File list box looks like.

                           +------ C:\BEAM\*.BCB -------+
                           | [A:]          file0002.bcb |
                           | [B:]          file0003.bcb |
                           | [C:]          file0004.bcb |
                           | ..\           file0005.bcb |
                           | \DIR_A        file0006.bcb |
                           | \DIR_B                     |
                           +----------------------------+

          Now you can perform the following actions:

          Keyboard: (two methods)

                1.  You can move around the file list by using then  arrow
                    keys, Home, End, PageUp, and PageDown.  When your  po-
                    sitioned on the  file name  you want,  press Enter  to
                    load Beam Cookbook file.

          ________________________________________________________________


                2.  You can move through the file list by using the first-
                    letter selection.  Pressing the  B key,  for  example,
                    takes you to the first file  name starting with B  (if
                    there are no file names  beginning with B, the  cursor
                    won't move). Press B again and you'll go to the next B
                    file name starting with  B, and so  on. If you've  ex-
                    hausted the letter B, you're brought back to the first
                    one. Holding down the Shift key and pressing takes you
                    to the first subdirectory that begins with the  letter
                    B. When you're positioned on  the file name you  want,
                    press Enter to load Beam Cookbook file.

                    You can  select  a  different directory or  drive  by
                    pressing Enter when you're  positioned on the one  you
                    want.

                    Press Esc to exit File List without selecting a file.

          Mouse:

                    You can move  around the file  list by clicking  (left
                    button) on the file you want. To select the file  just
                    click again. You can  select a different directory  or
                    drive by the same method.

                    To exit without  selecting a file  click on the  close
                    box or click using the right mouse button.

          If your beam problem contains data that you haven't saved,  Beam
          Cookbook asks if you want to save the file first before  opening
          the file you selected.

            
          OPENING A NEW FILE

          The F10|File|New command opens a new beam file with the  default
          name 'NONAME.BCB'.   This NONAME  file is  used as  a temporary
          file; Beam Cookbook prompts you to  rename the NONAME file  when
          you save it.

          If your beam problem contains data that you haven't saved,  Beam
          Cookbook asks if you want to save the file first before starting
          the  New file.

            
          SAVING FILES

          There are two  file commands you  can use to  save beam  problem
          data files to disk:


                                         61




                                 BEAM COOKBOOK 1.0
          ________________________________________________________________

              * Save saves the current beam file under the current name.

              * Save As lets you assign a name to a beam problem and then
                save it, or  save a beam  problem under  a different  file
                name.

          F2 is the shortcut for the F10|File|Save command.

          If you haven't saved the beam  problem before, or want to  store
          it in a different file, use the Save As command:

                1.  Choose F10|File|Save As.   Beam Cookbook  prompts  you
                    for the file name.   The current file  and path   name
                    are used as the default.  The default will be shown on
                    the input line.   If the  current file is  a new  file
                    ("NONAME.BCB") the input line is blank.  Here is  what
                    the input box looks like.

               +------------------- Save File As -------------------+
               |                                                    |
               +----------------------------------------------------+
               | OK                                                 |
               +----------------------------------------------------+


                2.  To use the default file name, press Enter, or click on
                    OK.  To use a different  name, enter a new name,  edit
                    the existing name, or enter a  path and /or file  name
                    using DOS wildcards, press Enter a get a list of files
                    in the directory you specified. If you don't specify a
                    file-name extension,  Beam Cookbook  adds the  default
                    extension .BCB.  (If  you specify a  different exte n-
                    sion, you'll  have to  include it  each time  you  are
                    prompted for a  file name.)   If you  don't specify  a
                    path the default directory is used.   If the line  is
                    blank the default directory is used and the  file-name
                    is *.BCB is used.

                3.  If the  file name already  exists, Beam Cookbook  dis-
                    plays an overwrite warning message.

                           +---------- Verify ---------+
                           |                           |

                4.  Choose the option you want:

          ________________________________________________________________

              * Yes overwrites the existing file.

              * No or Cancel interrupts the command and returns you to the
                main menu; you can then save the beam problem under a dif-
                ferent name.

          Beam Cookbook saves the beam problem in the specified directory.
          The beam problem remains onscreen, and you can continue  working
          on it.

          Assigning a file name

          File names can  be up to  eight characters long  and consist  of
          both letters and numbers. You can enter file names using  either
          upper- or lowercase letters.  Do not  use spaces in a file.  You
          can, however, use underscore character (_) to simulate   spaces,
          for example, PROB_12.

          When you name  a file, use  a name that  will help you  remember
          what is in the  file.  If  you share a  disk with other  people,
          it's a good idea to begin each of your file names with your ini-
          tials.  This ensures that all  your files will be displayed  to-
          gether, since  Beam Cookbook sorts them alphabetically.  You can
          also use  wildcards to  display only  your files;  for  example,
          RM*.* displays only files beginning with RM.

          Caution!
          If the name you  give is more than  eight characters long,  Beam
          Cookbook truncates it.   This will cause  problems if the  first
          eight characters of  two file names  are the  same. For  example
          BEAMPROB1 and BEAMPROB2 would be truncated to BEAMPROB, and sav-
          ing one would overwrite the other.

          It's best if you don't include an extension with the file  name.
          Beam Cookbook then adds  the default extension (.BCB)  automati-
          cally and  you don't  have to  include when  you open  the  file
          later.


            
          OVERRIDING THE DEFAULT DIRECTORY

          The default directory is the disk drive and directory  specified
          with  F10|File|Change  Directory  command  and  saved  with  F10
          |Options|Save Options command.

          When you use the file command, Beam Cookbook displays a list  of
          files in the default directory.  Unless you specify   otherwise,
          Beam Cookbook files are saved in the default directory, and Beam
          Cookbook looks there  when you  choose F10|File|Open to  open a
          file.

          ________________________________________________________________


          You can always  override the default  directory by specifying  a
          different one when Beam  Cookbook prompts you  for a file  name.
          You  can   also   access   a  different   directory   with   the
          F10|File|Change Directory command.  When you specify a directory
          with F10|File|Change Directory, files in that directory are dis-
          played each time you initiate a File menu command.

          Beam Cookbook preserves  the specified path  name when you  save
          the beam file.  Beam Cookbook  reverts to the default  directory
          when when you save other beam files.  This lets you access  dif-
          ferent directories without having to reset the default directory
          or include a path name with the file names.

          The File list box described on page 60 lets you access different
          directories and drives.

          To change the default directory temporarily,

                1.  Choose F10|File|Change Directory.  Beam Cookbook
                    prompts for a directory path  name and shows the  cur-
                    rent default directory path.

               +--------------- Enter.New.Directory  ---------------+
               | C:\BEAM                                            |
               +----------------------------------------------------+
               | OK                                                 |
               +----------------------------------------------------+


                2.  Either edit the existing default, or enter a new  path
                    name for the directory  you want.   If the disk  drive
                    differs from the current directory, include the  drive
                    designation, too.    If  you  leave  the  input  blank
                    (current drive) or key in a drive (drive letter  only.
                    'C' or 'C:') and press Enter  or click on OK, the  Di-
                    rectory Tree list will display.  From this you can se-
                    lect a new directory.  (See  "Using the Directory Tree
                    list box" on page 64.)

          Beam Cookbook uses the new  directory until you specify  another
          one with F10|File|Change Directory, or exit Beam Cookbook.   You
          can always override the temporary directory by specifying a  di-
          rectory when Beam Cookbook prompts you for a file name.

          You  can   make   the   temporary   directory   permanent   with
          F10|Options|Save Options command (see page 57) or  automatically
          when exiting Beam Cookbook (see File Directory on page 56).

          Using the Directory Tree list box

          The Directory  Tree  list box  displays  all directories  for  a
          specified drive.  This is where you point to (or move the cursor
          to) a directory name and choose the directory you want.  Here is
          what the Directory Tree list box looks like.

                               +-------------------+
                               |                   |
                               |    +--C:\         |
                               |    |              |
                               |    |--+--DIR_A    |
                               |    |  |           |
                               |    +  +----DIR_B  |
                               |    |  |           |
                               |    |  +----DIR_C  |
                               |    |  |           |
                               |    |  +----DIR_D  |
                               |    |              |
                               |    +---DIR_B      |
                               |                   |
                               +-------------------+

          Now you can perform the following actions:

          Keyboard:

               You can move around the file list by using then arrow keys,
               Home, End, PageUp, and PageDown. When your positioned on
               the directory name you want, press Enter to load Beam Cook-
               book file or press Esc to exit.

          Mouse:

               You can move around the directory tree by clicking (left
               button) on the directory you want. To select the directory
               just click again.

               To exit without selecting a file click on the close box or
               click using the right mouse button.

                                 ADVANCED COMMANDS

          Advanced commands are used to change input data without deleting
          and/or reentering data.  The main reason for  these commands is
          to analyze different cases using the same basic beam  configura-
          tion.

          This chapter describes how to
              * activate or deactivate complete input window entries

              * activate or deactivate a single entry

              * using  activate/deactivate complete  input window  entries
                with activate/deactivte single entries.


            
          PRIMARY ACTIVATE AND DEACTIVATE COMMANDS

          The primary commands are initiated by pressing the Alt-D keys to
          deactivate or by  pressing the Alt-A  keys to  activate.   These
          commands will deactivate/activate all inputs in the active  win-
          dow.  This  is referred  to as the  primary status  of an  input
          field.  The default primary status  for all input fields is  ac-
          tive.  This command can be used on following input windows:

              * Beam Configuration   (can only be used in the variable I
                section when moment of inertia type is set to variable I)

              * Supports

              * Concentrated Loads

              * Moments

              * Uniform Loads

              * Ramp Loads

              * Hinges

              * Moment Connectors

          See the section "Using both  primary and secondary commands"  on
          page 67.

          ________________________________________________________________


            
          SECONDARY ACTIVATE AND DEACTIVATE COMMAND

          If the input field is active it will deactivate it.  If the i n-
          put field is deactive it will active it.  This is referred to as
          the secondary status of an input  field.  The default  secondary
          status for all input fields is active.  This command will toggle
          the secondary status from active to deactive or deactive to  ac-
          tive.   This command  has a  different  purpose if  the  primary
          status is deactive (See the section "Using both primary and sec-
          ondary commands" on page 67).  This command can be used  on fol-
          lowing input windows:

              * Beam Configuration  (can only be  used in the variable  I
                section when moment of inertia type is set to variable I)

              * Supports

              * Concentrated Loads

              * Moments

              * Uniform Loads

              * Ramp Loads

              * Hinges

              * Moment Connectors

            
          USING BOTH PRIMARY AND SECONDARY COMMANDS

          Each input field has two statuses, primary and secondary.   Both
          statuses must be active for the input to be used.

          The primary activate (Alt-A) and primary deactivate (Alt-A) com-
          mands will only change the primary status.  These commands  will
          not change the secondary status.

          The secondary command  (F4) has  two purposes  depending on  the
          primary status.  If the primary  status is active, this  command
          will toggle the secondary status.  If the primary status is  de-
          active, this will change the primary status to active.

          An example for using  both commands is when  you want delete  20
          out of 25  concentrated loads.   You would first  use the  Alt-D
          command which would deactivate all the  loads.  Then use the  F4
          command on the 5 loads you want active.
