Hi Colin
This does what you want:
while (($k, $v) = each %picDetails )
{
# do stuff to $v;
}
Note that to modify the hash's copy of $v you would have to change
$picDetails{$k}.
HTH,

foreach my $key (keys(%picDetails)) {
my $val = $picDetails{$key};
# do stuff to val
}
or
while (my ($key, $val) = each (%picDetails)) {
# do stuff to key or val
}
(foreach may work here as well, but I have always preferred while's for
some reason)
perldoc -f each
perldoc -f
