Use IFGACB macro to map the fields in the ACB. Establish addressability to the
generated ACB area and plug the DDNAME into the ACB ddname field. The other
macro of interest is IFGRPL for manipulating the RPL.

Given that the DDNAME value is a character string, I suspect the OP
would like the macro to take an address of a character string as
an argument.
