Is there a way to force a variable to walk through the alphabet the 
way it can numbers?

ie: for numbers:  $k=0; $k=$k+1; would give you 1

for letters $k='a'; $k=$k+1; this won't give you 'b'; but is there 
any way of doing this that will?

Actually, also:

[EMAIL PROTECTED]:~# perl -e "for('a'..'z') { print }"
[EMAIL PROTECTED]:~#
.. and ... are slightly different operators.
