ADDRESS IPCS Instruction

To enter subcommands from a REXX EXEC, use the ADDRESS IPCS instruction. ADDRESS IPCS changes the host command environment to IPCS. The IPCS host command environment is available only when you run the EXEC from an IPCS session.

The example in Figure 1 is a simple REXX EXEC that changes the host command environment to IPCS for all commands and then enters the STATUS and LIST subcommands.

/* REXX */

Address IPCS

'STATUS'
if rc > 0 then signal Exit
'LIST 0. LENGTH(100)'

Exit: exit

You can also use ADDRESS IPCS for a single command. Figure 2 gives an example.
