number of letters for filename

[yi@ecn.purdue.edu (Juneho Yi)]

I started to use MCL and my question may not be
about  MCL itself.
In order to make the name of lisp file name more meaningful 
and easy to remember, I use many letters for file name.
But only 31 letters are allowed for filename.
Is there anyway to extend the number of letters for filename 
over 31 ?

Thank you.
