PASUG: November 2000 Rexx Presentation

Note: This website is using CSS and other modern web techniques. Just as you migrated from DOS to a more modern operating system, perhaps it is time to use a newer browser. Anyway, we have tested this site with a variety of old browsers (1.0 browsers my have some trouble) and, while most of them will display the site's content, it may not be very pretty.

BASIC REXX

Barry Mann

Presented to the PACS (Philadelphia Area Computer Society) OS/2 SIG November 15, 2000. Note that, since the meeting, we have made a few minor corrections to the presentation, added some additional comments to the programs, and added some code to OS-2_SIG.CMD to create the ZIP files for this web page.

If you would like to download the presentation, click on one or more of the links below. The JukeBox demo is optional. Since commercial packages use VROBJ.DLL, you may not need to download a copy, but you need the correct version. If you have the wrong version of VROBJ.DLL, JukeBox.exe will not load. The version included here will replace all earlier versions.

JukeBox Demo (99KB) A multi-threaded GUI (Graphical User Interface) application. This imaginary CD JukeBox player was written using the VXREXX development package. All user supplied code was written in REXX. Note, this is strictly a proof of concept, it will not actually play anything.

VXREXX run time dll (389KB) Download the DLL only if you need it.
