Declare PARM as pointer since OPTIONS(BYVALUE) is in effect.

Please correct me if I am wrong.

Only one PARM value can be passed. But you can pass two values in one with delimiter.

Substring the PARM in program into two(in your case).

Or use input file as values grow.

What does this 'BYVALUE' stand for?

This info is from MVS QW.

When you specify BYVALUE, compiler puts the value of the argument in the parameter list.

When you specify BYVALUE, a dummy argument is not created; however, as is also true for dummy arguments, any change to the corresponding parameter in the called routine will not be visible in the calling routine.

BYVALUE can be specified only for scalar arguments and parameters that have lengths and sizes known at compile time.

Please see about BYADDR to contrast with BYVALUE.
