Tommy's right, as usual.  And the Overlay() technique is the one I use, too.


I did, however, want to point out that one usually wants to use the MOVEA (not the MOVE) op-code when dealing with arrays. Details too lengthy to go into here so check either the RPG reference manual or Cozzi's book.

Does your DS look like this??

D                     DS
D ARC                           10a
D ARD 1a DIM(10) Overlay(ARC)

If so then anything you move into ARC should automagically populate the
array.  Likewise if you load the array it should automagically load the
char field.

Thanks Tommy, does it work the other way? I noticed that a plain MOVE
does
not actually do it,
MOVE      J8CMNT        ARC

the array stays blank after this statement.

Generally when I have to do this I use the D specs...it's easier &
more
efficient (IMO)...

D                     DS
D Alpha                           10a
D ARD                             1a   DIM(10) Overlay(Alpha)

Now the array can be referenced via array element or as a 10 byte char
field.  Not to mention you no longer have to "move" the array data.
Both fields point to the same block of memory.


Thanks,
Tommy Holden

and try to move this field into a 10 pos. field in a PF but prgrm does
NOT
