You can add macro definitions, and members containing assembler source statements that can be read by a COPY instruction, to a macro library. Use the LIBR utility program for this purpose. Details of this program and its control statements are contained in the applicable System control statements publication. The following example adds a new macro definition, NEWMAC, to the system library, PRD2.PROD.

// JOB CATMAC
// EXEC LIBR
ACCESS SUBLIB=PRD2.PROD
CATALOG NEWMAC.A REPLACE=YES
           MACRO
           NEWMAC &OP1,&OP2
           LCLA   &PAR1,&PAR2
