Re^3: CGI Action call

my %hash = shift;

This can never work and likely never is what you intend it to be. See shift.

Most likely, the correct code you wanted is

my %hash = @_;
[download]

... given the way you call completeResultHash.

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');` [download] These are all the same.	[reply] [d/l]

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]
