Ouch.. that's really wrong.
read up on:
perldoc perldata
(search for Typeglobs)
Here is a snip from the manpage:
Typeglobs and Filehandles
Perl uses an internal type called a typeglob to hold an
entire symbol table entry. The type prefix of a typeglob is
a "*", because it represents all types. This used to be the
preferred way to pass arrays and hashes by reference into a
function, but now that we have real references, this is
seldom needed.
The main use of typeglobs in modern Perl is create symbol
table aliases. This assignment:
*this = *that;
makes $this an alias for $that, @this an alias for @that,
%this an alias for %that, &this an alias for &that, etc.
[snipped the rest]
There is more into it than that, which the rest of the docs explain (I
think).
Can you tell us whereelse 'input' is in your code and post some of that
code?
It could be anything, (FILEHANDLE, %HASH, @array, $scalar).
