Re^4: CGI Action call

My undestanding:

my $a = shift; 1st item
my $b = shift; 2nd item (if exits etc since it was bumped up to top by
+ pervious shift.

my ($a, $b) = @_;

my $a = $query->param('a');
my $b = $query->param('b');

These are all the same.

What you wrote above has nothing to do with the assignment of subroutine parameters. `shift` will only move one element from the parameter list. A hash will occupy multiple slots in the parameter list. You need to learn about how Perl passes parameters in subroutine calls. `param(...)` is only for CGI parameters and has no bearing on subroutine parameters.	[reply] [d/l] [select]

param(...) is only for CGI parameters and has no bearing on subroutine parameters. Winder why I thought or assumed that?	[reply]
