Ah, awareness ... good to see on a thread with a sad amount of misinformed absolutism. For any still under the thrall of absolutist teaching in their formative youth, please consider C's "break" which ends any switch case which does not fall through to the next. It _is_ a goto. (They all goto the same place.) The aliased name is just syntactic candy. In the ITUT Specification and Description Language (SDL), there is a JOIN command, much used to avoid unreliable code duplication in the event-driven embedded systems on which it is used. It is a GOTO, but the different name makes it legit in the eyes of those with GOTO-phobia. It is possible that impressionable undergraduates missed one word in the lecture "goto should almost always be avoided". They may also have failed to realise that the lecturer was talking to ultimate noobs, not experienced programmers. > Just look at our beloved HAL code ( coded in C ) > you will see lots of goto statements for error cleanup/messages. > makes the code easy to follow and clean. > > besides if someone wants to write 'bad' gcode with gotos that > work, who are we to tell them how to program :) It is clumsy and confusing to use them where a more structured, and therefore more descriptive, construct is available. Not for nought is it said that a determined programmer can write fortran in any language. Erik -- [Perl is] more like a tank than a mine field. It may be ugly, but it shoots straight and gets you where you're going, if you don't mind a few squashed daisies. - Larry Wall ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
