I.1 Library Routines

ACUCOBOL-GT has a large set of library routines built into the runtime system. These routines may be accessed via the CALL verb. This appendix describes each of these routines in detail. The routines are listed in alphabetical order.

In the following descriptions, the phrase "Numeric parameter" indicates a data item or literal that contains a numeric value in any of the following formats:

Signed or unsigned COMP-4 (or internal equivalent such as COMP-X)
Unsigned PIC 9 USAGE DISPLAY
PIC X containing digits (other data ignored)
Unsigned numeric literal
Alphanumeric literal containing digits (other data ignored)

Note that any routine that has a GIVING phrase specified in its USAGE may omit that phrase. If this is done, then the routine's return value will be placed into the special register RETURN-CODE instead.
