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.
