I know what function is most likely throwing this error, but I don't
know where the error is and the failure isn't remotely helpful. After
throwing the error, TDSI stops processing and does not exit.

I found and corrected the error (pushing 325 as a Byte instead of
Short); but that error really could've been more helpful.
