PERIODIC.ZzIP contains the following:

 - PERIODIC.COM
 - PERIODIC.DAT
 - PERIODIC.ICN
 - PERIODIC.TXT
 - PERIODIC.PCX

PERIODIC-LX is a graphically driven periodic table database optimised for use on HPLX palmtops (will also run on a desktop).

Its use is simple and largely self-explanatory. At all times, all available command keys are displayed at the bottom of the screen.

The programme comes containing a selection of data on each of the elements, which can be accessed by pressing F2 and F3 with the cursor positioned over the element. Part of this data (that accessed by pressing F3:Note) is a free-form note card that can be modified to contain any data useful to the user. This information is stored in a separate file, PERIODIC.DAT. It can easily be modified by using any text editor, and resaved in ASCII/plain text format. Each card is 47x8 characters in size, and care must be taken to maintain these dimensions when modifying the data, otherwise the resulting output when the programme tries to access the file will be jumbled information, or an error. The easiest way to overcome this is to have your Editor (eg MEMO) set to REPLACE (rather than INSERT) mode. This way no characters are actually added or removed, only typed over. The current data (.dat) file may be kept, modified, or serve as a template only: all of its text, including the borders, can be modified.

All care has been taken in the writing of this programme, but the author cannot accept any responsibility for any errors in the data, or consequences of using the programme.

This programme can be distributed freely, but please do so in its original ZIPPED format containing all four components as listed above.

Any comments or questions will be happily received at the above email address. (In fact, even simple aknowledgement that this programme has been used will help motivate me to update this and work on other projects).


APPENDIX: Installation on the HPLX.
-----------------------------------

Unzip/copy all files into the same directory (the naming of which is unimportant, but A:\PERIODIC\ would do as an example.

From the Application Manager desktop, press F2 (ADD).

Input the following data as required:

 Name:      PERIODIC
 Path:      a:\periodic\periodic.com|
 Comments:  
 Icon:      (should automatically display icon when selected)

And hit F10 when done.
