CWA CONSIDERATIONS

CICS communicates with CA Dispatch by way of a 4-byte area in the Common Work Area (CWA).

A four-byte area must be identified and reserved for the exclusive use of the interfaces. Calculate the displacement from the beginning (relative 0) of the CSA to the reserved area.

Important! CSA definitions must be mapped out with extreme care. If displacement calculations are in error, unpredictable results in the CA Dispatch/CICS interface and/or other applications utilizing the CWA may occur.

The transaction ID, specified in the source for module DSUCFC3 in the user modification, also needs to be changed to match the second transaction ID specified in Step 4 of the installation worksheet.

Receive and Apply the DSINCI1 user modification

Use SMP to receive and apply the DSINCI1 user modification. SMP will assemble and link the source modules defined in the user modification into the CAI.CADSLOAD data set.
