VAL_ Error Handling
The error handling strategy used by the VAL_ routines consists of
returning a bad function result under the following circumstances:
- If STATUS is not set to SAI__OK when the function
is invoked.
- If the BAD argument is set to .TRUE. and any of
the input arguments is bad.
- If any numerical error occurs during evaluation of the function -- in
this latter case an appropriate error code will also be returned via the
STATUS argument.
