CHECK

Default: CHECK 1

Placement: Anywhere

Scope: In each separately compiled program, the last CHECK in the program

unit determines the check level for the code block being produced.

Dependencies: None

check-level What is Checked Comments

0 Nothing CHECK 0 results in the fastest execution time.

1 (default) Nothing CHECK 1 might have a different meaning in

future versions of HP COBOL for HP NonStop

systems (“HP COBOL”). For the fastest execution

(and no subscript checking) in current and future

versions of HP COBOL, specify CHECK 0.

2 Validity of subscripts

and indexes

3 Validity of subscripts,

indexes, and reference

modifiers

Specifies the maximum level of checking that

HP COBOL currently provides.

4-15 Validity of subscripts,

indexes, and reference

modifiers

4 - 15 might have different meanings in future

versions of HP COBOL. For the maximum level of

checking that HP COBOL currently provides,

specify CHECK 3. For maximal checking, specify

CHECK 15 (which could increase the program’s

run-time overhead in future versions of

HP COBOL if additional checking levels are

implemented).
