Maybe I should tell you what fixed it:
The "param" was a string so enclosed it in single quotes.
Thanks!

If it's a variable, a

If it's a variable, and not declared, qualify it using "my or local".
Else, if it's a string that you want pass to the function, use single

Peter,
#!/usr/bin/perl -w
use strict;
my %date_formats = (
ccyymmdd => { now => sub {
my @arr = localtime();
print 'Year ', 1900 + $arr[5] . ' Month '. sprintf("%02d",$arr[4] + 1)
. ' Day ' . sprintf("%02d",$arr[3]);
}
} );
& { $date_formats{ccyymmdd}{now} };
Same output as previous
Peter
