Using the Standard URT Selection Logic

The CA Datacom CICS Services URT selection module determines the proper URT against which to process each request. This selection is based on the logic described following and diagrammed in Category 4: All Other User Commands. DCCTFPR returns the number of the selected URT in register 15. If it does not find a valid URT to satisfy the current request, DCCTFPR places a negative value in register 15.

The basic logic of the search relies on the naming scheme of the URTs. The 5-character prefix is ignored and the 4-digit number is assumed to start at 0001 and end at the MAXURT count. This number is the URT identification. This number determines the order of any hashing synonym strings.
