The parse macro instructions

Use the parse macro instructions in your Command Processor to:

Build a PCL describing the valid command or subcommand operands.
Establish symbolic references for the PDL returned by the Parse Service Routine. The labels used by your Command Processor on the various parse macro instructions allow you to access the fields in the DSECT which maps the PDL.

See Table 1 for a description of the parse macro instructions and their functions.

Figure 1 shows the interaction between a Command Processor and the Parse Service Routine.
