TIRFDTTS

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

DATETIMESTAMP converts the date part of a timestamp value into a valid date.

DATETIMESTAMP generates the following COBOL statements:

Statement

Quantity

Call

1

Compute

1

Move

3

Initialize

1

IF

1

Heavy use of DATETIMESTAMP can drastically increase CPU costs.

Hints

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

  • use DATETIMESTAMP once for the desired timestamp

  • save the date returned in a local view

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

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

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

Example (COBOL External Action Block)

In this example, one COBOL statement is needed to convert the date part of a timestamp value into a valid date.
