Oops, hit send by mistake. This problem all seems to be about mistakes...
Thanks to all who replied.

I did indeed have 3 hash tables... Duh (Must have been Friday afternoon).
The central problem was calling '&{${$date_format{$format}}{now}}()'

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
I saw Jenda's note and I suggest the code needs simplification.
