Using REXXUTIL

If you're using REXXUTIL very often and your PC has enough memory (8 MB or more), you should load REXXUTIL in the STARTUP.CMD.

Example for STARTUP.CMD:

 
/* Important: STARTUP.CMD must be a REXX program to load REXXUTIL!    */
  call RxFuncAdd "SysLoadFuncs", "REXXUTIL", "SysLoadFuncs"
  call SysLoadFuncs
  exit 0

Using REXXUTIL if booted from diskette

If you've booted OS/2 from diskette, you can use REXXUTIL in the following circumstances:

• The stub program to load the REXX support is BOS2REXX.EXE
  
• The OS/2 DLLs normally in the directory \OS2\DLL are accessible through the LIBPATH. Of course, these DLLs won't fit on a diskette. But they may be on a hard disk or a codeserver.
  
• And last you must load each function from REXXUTIL by hand with RxFuncAdd. You can't use SysLoadFuncs if booted from diskette!

You can't use the WPS related functions from REXXUTIL if booted from diskette, but mostly all other functions work fine. For example I've tested the following functions:

• SysCls 
  SysCurPos
  
  SysCurState
  
  SysDriveInfo
  
  SysDriveMap
  
  SysGetKey
  
  SysMkDir
  
  SysOS2Ver
  
  SysRmDir
  
  SysTempFileName
  
  SysTextScreenSize

  Note: see also the DLL CLTRUTIL included in the OS/2 WARP Server / OS/2 WARP Connect See also New REXXUTIL functions in Object REXX.
