Enhanced Visual Rexx (EVRexx) is a function package which enables the use 
of PM dialog-windows from REXX-procedures without detailed knowledge of PM 
programming. 
Description from the author: 
"This package was inspired by VREXX, a similar package written by R.B.Lam 
of IBM T.J.Watson Research Center 
VREXX has a number of limitations which are overcome with EVRexx: 
   *  EVRexx can be used by more than one process at a time. 
   *  With EVRexx you can (and must) define your own dialog windows. 
      Therefore it is possible to mix controls. 
   *  EVRexx allows modeless dialog windows. 
   *  Recovery of system resources in case of fatal (REXX-) errors. 
   *  Dialog windows are entered into the window list 
 
 The price you pay for all the enhancements of EVRexx is that the package 
 is not quite as easy to use as VREXX. In addition, the graphic 
 capabilities of VREXX are not yet implemented in this release of EVRexx. 
 To use EVRexx, you have to code the appropriate function calls in a 
 REXX-program and you have to supply a resource DLL with all the dialogs 
 you want to show. Although a resource compiler and a linker are part of 
 OS/2, it is quite cumbersome to design dialogs without a dialog editor 
 (like the one supplied with the developer's toolkit). The dialog editor 
 creates a resource script file which you would otherwise have to create 
 by hand. The script file is compiled by the resource compiler and linked 
 to a DLL by a linker."
