Specifying PL/I run-time options
The host server program is written in the PL/I language. Like most PL/I programs, aspects of its execution environment can be controlled by run-time options.
You can specify run-time options in the PARM operand on the JCL EXEC statement.
//STEP EXEC PGM=AUPTCPS,PARM='SPAE,SPIE/CASE=MIXED'
The PARM value has the format:
'run-time options/program parameter'
The program parameter is passed to the program. The host server program accepts its configuration parameters in this way.
For more information about run-time options for PL/I programs, see z/OS Language Environment Programming Guide.
