my %myNEWhash =
map { $_, delete $myhash{$_} } grep /^1\D/, keys %myhash;
You obviously should have put that line in its right context. It was
suggested in connection with Edward's question:
http://www.nntp.perl.org/group/perl.beginners/67638
and it combines the grep(), delete() and map() functions.
Now, if what you want to do is learning how the map() function works,
the above line may not be the best starting-point, but you'd better
start with studying the docs for map():
perldoc -f map
