Hi, WARNING: If you run these scripts, you will probably
get character corruption of your terminal, which can be
cleared with "reset". My first question: is there a simple
print code that I can print as the last line of my script to
reset the screen without losing the data printout?
If I type clear or reset after the script runs, it wipes
out my previous output. Is there some way of printing
a last line, say
print '[[asc', "done\n" ;
or something similar that will just reset my next line only?

Question 2:
I'm playing with a homemade virusscanner.
I've learned to do binary regexes, learned the value
of precompiling regexes, and now I'm working on
storing the precompiled binary regexes to a file
using Storable.

What I can do sucessfully, is convert hex signatures
to binary values, and store them in a hash via Storable.
I can retreive the hash, and do regexes sucessfully on
binary files.

What I want to do, is precompile the binary regexes and
store them with Storable. This isn't working for me, and
I'm stumped.
I've tried everything in my small toolbox, to get
$sigs{$name}= qr/\Q$valbin\E/;
to be accurately recovered.
Tried
"qr/\Q$valbin\E/";
and
quotemeta qr/\Q$valbin\E/;
with differing results.

2 scripts below demonstrate my roadblock.
