Example 1:

Enable ooRexx, set the filename extensions to be used to “.REXX” and “.REX” and set subroutine style
for passing arguments to the Rexx script.

REXX ENABLE OOREXX

REXX EXTENSIONS .REXX;.REX

REXX MODE SUBROUTINE

Example 2:

Enable Regina Rexx and set the search path for the Rexx scripts to “D:\MVS\SCRIPTS”, but disable the
search in the system path. Set the filename extensions to be used for the Rexx scripts to “.REXX”, “.REX”
and “.RX”.

Finally set the message and error prefixes to RXMSG and RXERR and enable displaying the HHC17503I
and HHC17504I messages after a Rexx script has been finished.

Use the default setting for the argument passing style.

REXX ENABLE REGINA

REXX PATH D:\MVS\SCRIPTS

REXX SYSPATH OFF

REXX EXTENSIONS .REXX;.REX;.RX
