Looks like V5R3 enhanced SETDPAT instruction to increase maximum length of
packed variable from 31 to 63.  That's great, thanks, but, when I try to
display a PKD(63,0) data pointer on V5R3 in OPM debugger, the OPM debugger
dumps with MCH0601, "Space offset **** is outside current limit for object
****"

DCL DTAPTR DATA AUTO;
DCL DD     ATTR AUTO CHAR(7);
DCL DD     BIG  AUTO CHAR(32) INIT(
 X"123456789012345678901234567890123456789012345678901234567890123F");
CPYBLA     ATTR, X"03003F00000000";
SETDPADR   DATA, BIG;
SETDPAT    DATA, ATTR;
BRK        "LOOK";
RTX        *;

and then

STRDBG ...
ADDBKP LOOK
CALL ...
DSPPGMVAR DATA

then MCH0601 occurs.   Work around?
