CICS VSAM Transparency for z/OS, Version 1.2


Notes for CTLRECF

The exit must build the key field every time it is called, regardless of whether the call is to process the control record or a record in the HLL_ITEM table. It also has to consider that it may be invoked several times in the same call.

This is described in FBE for a key or AIX field.

Several other points should be noted: There are more efficient ways to code this program but a key objective is to make it easy to understand.
