REXX Utility Functions (RexxUtil)


RexxUtil is a Dynamic Link Library (DLL) which provides the OS/2* REXX 
programmer with many versatile functions.  Primarily, these functions deal 
with the following: 
   o  OS/2 system commands. 
   o  User or text screen input/output (I/O). 
   o  OS/2 INI file I/O. 
 
 RexxUtil requires that you are already running under OS/2 2.1 (or a later 
 version of OS/2) with OS/2 Procedures Language 2/REXX installed. 
 To be able to use a RexxUtil function in a REXX program, you must first 
 add the function using the built-in function RxFuncAdd. 
 Example: 

 call RxFuncAdd 'SysCls', 'RexxUtil', 'SysCls'
 
 
 The above example would add the SysCls function so that it can be used. 
 The RexxUtil function, SysLoadFuncs, will automatically load all RexxUtil 
 functions.  To do this from within a program, add the following 
 instructions: 

 call RxFuncAdd 'SysLoadFuncs', 'RexxUtil', 'SysLoadFuncs'
 call SysLoadFuncs
 
 
 Once the RexxUtil functions are loaded by SysLoadFuncs they are usable by 
 all OS/2 sessions. 
 The RexxUtil functions are listed when you select the + sign beside this 
 topic in the Contents.
