Parameters specified in the JCL PARM parameter are passed to the program using the same rules as the mainframe. Options specified in the parameters string are separated from any application parameters by a slash (/) character. For example:
PARMS(application-parameters/run-time-options)
The linkage area used when passing parameters is:
01 PARM.
03 PARM-LENGTH PIC 9(4) COMP.
03 PARM-DATA PIC X OCCURS 100.
