Re: ref 'n typeglob

You attempted to solve this wrong two ways and missed the one "right" way. First - my() variables are not accessible via the symbol table and so typeglobs have no place in this discussion. Second - you don't need the prototype because - Third - @_'s elements are aliased to the actual variables.

In mysub tie the $_[0] variable directly. Don't shift it, don't pop it - you have to access it right inside the array.

Just as a light warning... diotalevi's method works fine but be aware that if you ever call `my_sub("literal")` (or similar), you will end up with a fatal error of `Modification of a read-only value attempted at ...` (with the file and line number being in your package at the tie; you may want to trap that error and carp it out to the caller). bbfu Black flowers blossom Fearless on my breath	[reply] [d/l] [select]
