ILE COBOL Language Reference
- RANGE indicates that at run-time, subscripts are verified that
they are within the correct ranges, but index ranges are not verified.
Reference modification and compiler-generated substring operations are also
checked. RANGE is the default value.
- NORANGE indicates that ranges are not verified at run
time.
- Note:
- The RANGE option generates code for checking subscript ranges. For
example, it ensures that you are not attempting to access the 21st element of
a 20-element array.
The NORANGE option does not generate code to check subscript ranges.
