Re: Forking On Foreach Keys In Hash, Passing Hash To Sub, And Speed/Efficiency Recommendations

You need to dereference the hashref in your subroutine.

$hashref{$key} = $npanxxcnt;
[download]

needs to be:

$$hashref{$key} = $npanxxcnt;
[download]

${$hashref}{$key} = $npanxxnct;
[download]

Also, your subroutine returns values but they are not stored anywhere in the calling program.

Personally, I find `$hashref->{$key} = $npanxxcnt;` [download] to be a more palatable form.	[reply] [d/l]
