Q:
What's a "blocked" TSQ record and why would I want them?
A:
For CICS/QSort, a "blocked" TSQ record is similar to a disk file "block" of records, in that a single contiguous area contains multiple logical records. For example, if you have TS records that would normally be 100 bytes each you can write each of them as a single 100-byte record, or you could "block" them into an area that contained 8 of the 100-byte areas. This would reduce the number of EXEC CICS WRITEQ/READQ calls necessary to process the same data to about 1/8 of the calls required for the 100-byte per TSQ record method.
Q:
Does QSort support the newer 16-byte TSQNAMEs?
A:
To sort temp storage queues with 16 byte names, EXEC CICS LINK to SMQSORTD or SMQSORTE. For 8-byte TSQ names, LINK to SMQSORTA or SMQSORTB.

Q:
Does Qsort use AUX or MAIN storage in CICS?
A:
By default, Qsort uses MAIN storage. Execute source member SORJZAP to change to AUX if preferred.
Q:
Can I sort temporary storage records using more than one sort key?
A:
You can specify up to 10 sort keys, each with its own "start", "length" and "direction" (Asending or Descending) values.
