OK here comes the newbie question.
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 ----------
Confused,
