I have a cobol db2 program(PGM A) where other program (PGM B) will call this program and passes some 50 fields data to PGM A. PGM A has some layout in which it receives the data from PGM B. And this layout has been copied in the linkage section pf PGM A. After getting the data, PGM A writes the data in a flat file in the same layout which it receives from PGM B. PGM B is a simple COBOL pgm. Please provide a JCL to run these programs.
