As a control structure a goto provides something that the "structured"
control structures do not provide: a permanent transfer of control.
Loops, and subprogram calls represent a temporary transfer of control.

Now a permanent transfer of control is almost never what you want. The
only use I have found is in implementing state machines but even then
a goto is not always the best solution. If you need access to state
information then you should probably not use gotos.

Fred McCall is probably correct in pointing out that we don't really
have enough information in the code fragment to judge is the use of
gotos was appropriate or not. However, I'm more than a little
suspicious when I see code like that.
