You map an IRD by updating the data set information using the manual mapping dialogs only.
This displays the screen in Figure 1.
--------------------- CICS VT: Update data set mapping -------------------------
Command ===> __________________________________________________________________
DIM name ===> APPLCTL_
Field build user exit name ===> ________ If selected, you must build
all fields for the data set
with the specified exit
I/R/D user exit name ===> MULTIRD_
I/R/D user exit processing order ===> A (B=Before,A=After,' '=Both)
I/R/D user exit language ===> L (A=Assembler,L=LE enabled)
DIM ready to be generated ===> Y
Enter=Update PF3=Exit
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.
