Test PPOPROC

The SYSPARMS PPOPROC command is used to invoke PPOPROC, and can also be used to flush it. This allows a new copy of the PPOPROC procedure to be invoked from a subsequent SYSPARMS command.

The &PPOALERT statement lets you generate test PPO messages which can be used to check the logic of PPOPROC without having to wait for a real occurrence of the message.

Note: The base PPOPROC procedure never uses a preloaded copy of the procedure, so it is unnecessary to use the UNLOAD command. Other procedures invoked from within PPOPROC will observe the normal preload conventions.
