From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, February 23, 2004 8:52 AM To: [EMAIL PROTECTED] Subject: counting differently 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?
