PEFR

These are the files you need. You can send them from the package contents below.

• pefr.com → A:\SOFT programa de DOS 33.4 KB
• pefr.dat → A:\_DAT configuración 16.0 KB
• pefr.icn → A:\SOFT icono, junto a su aplicación 200 B

No need to put pefr.txt: they are manuals, source code or supporting material. Read them here and save 3.4 KB on a 1 MB disk.

1. Copy pefr.com to A:\SOFT. They are DOS programs: run them from the DOS icon, or add A:\SOFT to the PATH in C:\AUTOEXEC.BAT to call them by name.
2. Copy pefr.dat to A:\_DAT, where the 200LX looks for configuration. Open it with Memo and adjust it before use.
3. If you edit a configuration file on the palmtop, make sure you leave a newline at the end: some programs swallow the last line without saying a word.
4. The .ICN files are icons: they go in the same folder as their application.

Derived from the package contents and the 200LX conventions. It installs to A: on purpose: C: is a RAM disk and every byte there is memory taken from the system.

Installation is easy. Put all files the same directory. This is a simple DOS programme that will run either under Application Manager (see appendix), or under DOS or DOS-based menu programmes (I run mine under HDM via MAXDOS, although the memory requirements are minimal). A 200LX compatible icon is included. This programme is optimised for the HP200LX, but will run 'as is' on a desktop, appearing rather low-res in comparison.

Use of the programme is relatively self explanatory. Input data as instructed at each prompt. ESCAPE or DELETE keys can be used to re-input data or end programme. You do not need to use ENTER after each entry, unless value is shorter than that prompted. The programme screens for incorrectly entered data and has some constraints on data ranges, as an error trapping mechanism. Be wary that although I have screened its performance, the programme may allow some nonsensical data through, or may even become confused if you purposefully try to enter garbage!

All care has been taken in the writing of this programme, but the author cannot accept any responsibility for any errors, or for the subsequent clinical application of programme output.

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:\PEFR\ would do as an example.

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