TIRFDYTS

TIRFDYTS is a called module supplied with CA Gen. TIRFDYTS is called every time an CA Gen action diagram uses the DAYTIMESTAMP function.

DAYTIMESTAMP extracts the day part of a timestamp. The numeric value returned will be a number between 1 and 31 inclusive.

DAYTIMESTAMP generates the following COBOL statements:

1

Compute

2

Initialize

IF

Heavy use of DAYTIMESTAMP can drastically increase CPU costs.

Hints

If an action diagram uses DAYTIMESTAMP more than once for the same timestamp:

  • use DAYTIMESTAMP once for the desired timestamp

  • save the day returned in a local view

  • use the local view instead of DAYTIMESTAMP for the remaining instances

  • pass the local view to the import view of any called action diagrams that need it.

If DAYTIMESTAMP is used in an action diagram that uses several CA Gen functions, or the action diagram has high CPU usage due to DAYTIMESTAMP, consider converting the action diagram to an external action block.

Example (COBOL External Action Block)

In this example, only two COBOL statements are needed to extract the day part of a timestamp into a numeric value.
