I found this in a template for creating subroutines, this is the base that is created when you use the template to create the subroutine.
So now the newbie part, why would you place "my $par1 = shift;" in the subroutine template, and what does it do??
Basically I am trying to find out if I need to modify the template or not. Any help would be greatly appreciated.
Oh and btw I looked at the shift function and it applies to the @_ array, which is not being used in this subroutine, and neither is @par1 , so my only guess would be that the template is creating a verifiably empty variable called $par1 .
sub Irfan { my $par1 = shift;
return ; } # ---------- end of subroutine Irfan ----------
Inside of a subroutine "shift" with no arguments is the same as "shift @_" and outside of a subroutine "shift" with no arguments is the same as "shift @ARGV". You can read all about subroutines in the perlsub document.
