I had the same problem at a prior job, causde by the intense aversion the
original programmers seemed to have to input validation of any sort.  Mostly
it was caused by users doing copy/paste, where the copied data had control
characters in it.  And then there was the entry of "codes" which didn't
exist in the appropriate codes file ... :(

I don't even want to get started on the evils of returning from a GOSUB via
any method but RETURN (using a flag setting to redirect from that point).
