REXX Tips & Tricks:REXXUTIL functions

This section contains hints about the functions from the DLL REXXUTIL.

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
