hi Gnanas,
when we quote procedure division using ws-parm,
var1,
var2.
ws-parm is linkage area for JCL passed from parm and var1,var2 are to be passed to pgm B.
Is ordering of variables not an issue. In main pgm B you have only var1 and var 2 so how data will pass to B. I am getting little confused. can you please explain.
regards,
rupesh gupta |

PROCEDURE DIVISION USING variables are only those variables being passed to the program. They are NOT the variables you are passing to another program. So in your example, you would NOT put var1, var2 in the program A PROCEDURE DIVISION USING statement. You would say in program A
| Code: |
CALL PGMB USING WS-PARM,
VAR1,
VAR2. |
and program B will have
| Code: |
| PROCEDURE DIVISION USING A, B, C |
where A, B, C are names in the LINKAGE SECTION of program B. There is no name congruence between the names of the parameters being passed in program A and the argument names used in program B -- you can call them anything you want. |
