TIRFSEC

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

SECOND extracts the second part of a valid time. The numeric value returned will be a number between 0 and 59 inclusive.

SECOND generates the following COBOL statements:

1

Compute

2

Move

2

Initialize

1

IF

1

Heavy use of SECOND can drastically increase CPU costs.

Hints

If an action diagram uses SECOND more than once for the same time:

  • use SECOND once for the desired time

  • save the second returned in a local view

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

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

If SECOND is used in an action diagram that uses several CA Gen functions, or the action diagram has high CPU usage due to SECOND, 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 second part of a time into a numeric value.
