CICS VSAM Transparency for z/OS, Version 1.2


Mapping an IRD

You map an IRD by updating the data set information using the manual mapping dialogs only.

This displays the screen in Figure 1.

The IRD MULTIRD is written in an LE/370 language and is invoked after the DDM has processed the SQL INSERT/ DELETE/UPDATE call. (The field value for I/R/D user exit processing order is A.)

When you map an IRD, the exit processing order is the main mapping option to consider.
