I was one of those ivy leage types and I can tell you that over 30 yrs
of programming in everything from direct opcodes in a DEC PDP unit up
through Honeywell, Unisys, IBM 3090's and every thing in the middle we
used a goto rarely and carefully but used them none the less. The trick
is to document how the entry point can be reached because if the same
goto is used multiple times across many thousands of lines of code then
there may be a better way to do it. Otherwise, go forth and goto. ( pun
intended ).
