REXX system commands

This part describes the REXX system commands.

You can enter these commands through System REXX as an MVS™ system command. See the section Communication with System REXX in z/OS MVS System Commands. Some UNIX commands may require mixed case arguments or run longer than the System REXX time limit. Communication with System REXX describes using lower case and other quote rules. It also describes how to override the default time limit and how to use command prefixes. In order to use z/OS® UNIX facilities, it is necessary to logon to the console with a user ID that has access to z/OS UNIX. Also, depending on the command, the use ID might also need to have superuser authority or be permitted to the BPX.SUPERUSER resource in the FACILITY class.
