18.5.1 REXX and SAA
Issuing commands to the surrounding environment is an integral part of REXX.
REXX is the only procedure language supported by the SAA to help provide
cross-system consistency. Procedures written in REXX according to the SAA
specifications can be transported to other SAA environments. For example, a
REXX exec in CMS can also run in a TSO/E environment if the exec does not use
system-specific functions or commands.
Only the ADDRESS command/instruction affects the host command environment
of the exec that uses the command/instruction.
