CHECK
CHECK
causes checking errors to be flagged.
In COBOL, index, subscript, and reference-modification ranges can
cause checking errors.
Default is: CHECK(ON)
Abbreviation
is: CH
ON
- Specifies that runtime checking is performed
OFF
- Specifies that runtime checking is not performed
Usage note: CHECK(ON)
has
no effect if NOSSRANGE
was in effect during compilation.
Performance
consideration: If you compiled a COBOL program with SSRANGE
,
and you are not testing or debugging an application, performance improves
if you specify CHECK(OFF)
.
