BOUNDOPT

Optimizes the code generated for subscripts.
Note: This directive is supported for native COBOL only.

Syntax:

>>-.---.-.----.--BOUNDOPT------------------><
   +-/-+ +-NO-+

Parameters:

None

Properties:

Default: BOUNDOPT
Phase: Generate
$SET: Initial

Dependencies:

Set to NOBOUNDOPT at end by BOUND.

Comments:

If BOUNDOPT is used, subscripts can be optimized on the assumption that they do not exceed the bounds of the table. In particular, any digits in a subscript above the size of the table may be ignored.

Can only be used when NOBOUND is specified. NOBOUNDOPT must be specified if a program references beyond the end of a table.

Example:

For a table with 50 entries, a PIC 9(3) subscript is treated as PIC 9(2), with the most significant digit ignored.
