Glad to be of service. Welcome to a life of programming, where the
palm meets the face on a regular basis... more frequently if you use
Microsoft Windows, tar, non-eight-bit-clean transmission methods, or
Adobe products, and extremely common as soon as you take over someone
else's code [1], but inevitable even without these stimuli. :)

Have fun!
