intra partition tdq's are read destructive because all intra partition tdq's
are stored in a queue and these are stored in a vsam dataset namely esds
if you want to use the deleted intraparttion tdq again u can specify in
DCT table as reuse=yes or by using put command in CICS.

I hope this answer may satsfies u
if any more information regarding ur question u got send to me
bye

HI KRISS, THANKS FOR U R REPLY.
I WILL WRITE U WHAT I UNDERSTOOD FROM U R ANSWER.
-- IN INTRAPARTITION TDQ, IN DFHDCT, REUSE=NO, SO IT IS NOT POSSIBLE TO REREAD THE RECORD IN INTRA TDQ.
BUT IN CASE OF TSQ, RECORD CAN BE REREAD, BECOZ, REUSE=YES IS BY DEFAULT I THINK. AM I RIGHT?
THANKS KRISS
