i want to need to define all variables within all of my subroutines. i want $sortby to be defined by $_[0] and $ascdesc to be defined by $_[1] etc.

i want these variables defined by the same variables outside of the sub. however, i don't want any changes to these variables to change their counterparts outside of my sub.

In reply to Re^2: passing variables to a sub by ag4ve
in thread passing variables to a sub by ag4ve
