When OS/2 is booted from diskette, you must use a special program to load the REXX support (normally, OS/2 boots from the hard disk and the WPS loads REXX support automatically).
The best program available to load REXX from diskette is BOS2REXX.EXE.
To create a boot diskette with REXX support do the following:
1. Create a boot diskette with, for example BOOTOS2.
2. Copy BOS2REXX.EXE to the boot diskette
3. Add the statement RUN=A:\BOS2REXX.EXE to the file A:\CONFIG.SYS
4. Add the directory with the files REXX*.DLL (\OS2\DLL) to the <LIBPATH in the file A:\CONFIG.SYS
5. Add the directory with the file REX.MSG (\OS2\SYSTEM) to the <DPATH in the file A:\CONFIG.SYS
Note: You may omit the third step. In this case you must init the REXX support manually with the command
This method allows you to load REXX support only if necessary.
(see also Using REXXUTIL; use LX lite - an compressor for OS/2 executables to create one (!) boot diskette with REXX support and other useful tools!)
Important: Do NOT kill the process with BOS2REXX! Your REXX programs might not act as expected if you do so! The process which initially starts the REXX support is required throughout the session because it handles the global data, semaphores and so on. This is true even if you restart BOS2REXX after killing it!
