This field is used to distinguish between normal tableBASE processing and other specialized types of tableBASE processing. Date-Sensitive Processing is the only special processing available at this time.

FUNCTION-ID = 0 for normal processing

FUNCTION-ID = 1 for Date-Sensitive Processing

FUNCTION-ID = 16 no longer required starting with Version 7. This used to be required for displaying the TSR Access Count in the LT command but as of Version 7, the CICS driver command processor defaults this field to 16 for the LT command.
