Description from the author:
"Rexx Dialog allows an OS/2 REXX script to open multiple PM windows with list and drop boxes, spin/push/radio/checkmark buttons, sliders, menus, etc. Add a full PM (i.e., visual) interface to a REXX script. Also, easily add a visual REXX interface to a C program. Much smaller than full-blown commercial Visual REXX packages, and it's free!"
This is a really great package for using the PM interface in REXX programs! I strongly suggest you take a look at Rexx Dialog before using (and buying!) one of the commercial visual REXX packages.
One disadvantage of this package: You cannot pass parameter to programs using Rexx Dialog. But, of course, there's a workaround for it.
Note: See the program REXXCC/2 which is part of REXXCC v3+ for an example of using Rexx Dialog.
Note: REXX Dialog seems not to work with Object REXX.
