Ralf,
Those flag variables, if named something explanatory provide status
information that is most valuable, specifically in debugging or influencing
the code to be performed at the target of the goto. My favorite is a
depth variable for recursive code. The other problem with goto, is that it
is a tailless kite. It provides no pointer to it's source once it gets where
it is going. I suspect that because of the violence done to block structures
and the loss of state information(currently, in Euphoria, you are always
in the main line, or in a procedure or function stack that leads back to
the main line), the overhead alone will prevent the use of goto's if
Robert is foolish enough to resurrect this long-dead canard for those
who haven't learned how to structure their logic yet. By the way,
routine_id() with call...call_back is a goto with many of the same effects.
