 Undefined subroutine main::some_routine_name called at script_name line
 XXX
 
 TIA

If they are miscodings then not really, mostly because Perl allows you
to choose subroutines/methods at runtime. So the interpreter can't know
a pri ori what subs need to exist. If you need to check for a sub to see
whether or not you should be calling it, for instance to see if an
object has a particular method you can use the UNIVERSAL::can function,
see perldoc UNIVERSAL for more info.

Of couse having said all that, aren't you testing ;-)

Undefined subroutine Error

was wondering is there away to check, with a perl code, to make sure the sub 
routine exists before displaying this system 500 internal error message. the
