- 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.
