Writing IPCS REXX EXECs

This section describes some techniques you might want to use for writing and debugging IPCS REXX EXECs.

Using IPCS and REXX Facilities for Writing REXX EXECs

Several facilities are available for use in writing a REXX EXEC. These facilities include both REXX instructions and IPCS subcommands.

The REXX instructions are:

ADDRESS IPCS
Use ADDRESS IPCS to change the host command environment to IPCS.
SIGNAL ON HALT and TRACE OFF
Use SIGNAL ON HALT and TRACE OFF to suppress unwanted error messages and trace records.

The IPCS subcommands are:

EVALUATE
Use the EVALUATE subcommand to retrieve data from a dump and store the data in a REXX variable.
NOTE
Use the NOTE subcommand for output from the REXX EXEC.

The following sections provide detailed descriptions of each of these facilities along with a summary, Putting the Pieces Together.
