No. But if in the same load module you do the above and Joe does
MYFOO DXD A
MYBAR DC Q(MYFOO)
then BAR and MYVAR will have different contents. In really old PL/I
compilers IBM put the Q-cons in the offset fields of instructions,
limiting the PRV to 4096 bytes.

No. But if PRVREG points to srage allocated with a length from a CXD, then
GETMAIN ...
L R2,BAR Point to unique offset
ST R1,0(PTVTRG,R2) Save my storage area for subsequent use
will do what the comments say it does. However, Don's suggestion (CEEPDDA
and CEEPLDA) is probably the best way to go.
