REXX checks

A REXX check runs in a System REXX address space in an APF authorized environment defined by System REXX. You identify it as a REXX check on the REXX(YES) parameter when defining the check to the system.

A REXX check makes it easy to issue system commands (using the AXRCMD function) and to analyze the output of commands issued. REXX also makes it easy to read data sets or to issue system commands, and parse the retrieved information

You can run System REXX checks in TSO and non-TSO environments.

The following figure shows the parts of a REXX check. The shaded items show the parts that a check developer must provide:
