PassErr
Passes an error to the next level.
If “errornum” is zero,
PassErr does not do
anything.
The
Else clause in the program should use ClrErr
or PassErr. If the error is to be processed or
ignored, use
ClrErr. If what to do with the error
is not known, use
PassErr to send it to the next
error handler. (See also
ClrErr.)
See
ClrErr program listing example.
