Hi
05 A PIC X(80)
05 B REDEFINES A PIC X(80)
is it possible to Move 'X' to all of variable 'A' without using the following solutions:


1.05 A PIC X(80) value all 'X'
2. Inspect A converting spaces to 'X'
3.Perform Para-Move varying i from 1 by 1 till i=80
Para-Move.
Move 'X' to B(i)

The solution should have Move statement and should not be any of the solutions mentioned above

Thanks
Have a nice day

CICS GUY

This statement moves 'X' to all bytes of the variable or moves to all the variable, please clear this query.

Code:

05 A.
    10 B      PIC X(01).
    10 C      PIC X(79).
05 FILLER     REDEFINES A.
    10 D      PIC X(79).
    10 FILLER PIC X(01).

MOVE 'X' TO B.
MOVE D TO C.


This propagates the X to every byte in A.

A word of warning Douglas, IIRC, the overlapping move does not work in the same direction on a SYSTEM 3.....Got burned bad on that during a 360/30 conversion..... icon_lol.gif

You are correct, this does not work on all systems, nor on all implementations of COBOL, but he asked for a solution for specific to IBM-370-COBOL.
