Reply with quote

Hi,
Is it possible to pass a variable declared inside a procedure to another procedure.

PROC1: PROCEDURE;
DCL A CHAR(20);
A = 'ABC';
CALL PROC2;
END PROC1;

PROC2: PROCEDURE;

PUT SKIP LIST('Value from PROC1' !! A);

END PROC2;

Now I get a compiler warning that A is implicitly declared.

Kindly help.

Why do you think it's called an internal variable?

If you want to pass it around, you'll have to use

Code:
PROC1: PROC;
DCL A CHAR(20);
A = 'ABC';
CALL PROC2(a);
END PROC1;

PROC2: PROC(b);
dcl b char(*);

PUT SKIP LIST('Value from PROC1' !! b);

END PROC2;
