Re: [MacPerl] unknown error question -- used only once --

Robert,

The particular error is caused by your using the variable
        $holdingThing
exactly one time.  If you think you used the same variable
somewhere else, one or the other is a typo or out of scope.

If want to use it just once and hate the message, just do something
above the "real" use like:
  $holdingThing = undef;
and, since you've used the same variable in the same scope more than
once, the compiler thinks you know what your doing.  :-)

Of course, one should declare all variables one doesn't need to be
global with the (Perl5) 'my' statement so they have restricted scope.
