Most gratuitous use of 'goto'

What's the most gratuitous, inane, innappropriate or just plain wrong use of the
gotokeyword you've seen? cheers, Chris Maunderwasnt this a non-coding forum!? :cool: Don't try it, just do it! ;-)

What's the most gratuitous, inane, innappropriate or just plain wrong use of the
gotokeyword you've seen? cheers, Chris MaunderI ran across some code where 'goto' was used to go to the end of a 'for' loop and do the next case. I think it's beause somebody didn't know about the continue statement. "When a man sits with a pretty girl for an hour, it seems like a minute. But let him sit on a hot stove for a minute and it's longer than any hour. That's relativity." - Albert Einstein

I said "goto" not "coding". There's a difference :P cheers, Chris Maunder

I have come across quite a few programmers that don't know about continue.

gotobed." I certainly felt that was inane, as well as just plain wrong. ;PShog9
I returned and saw under the sun, that the race is not to the swift, nor the battle to the strong...

What's the most gratuitous, inane, innappropriate or just plain wrong use of the
gotokeyword you've seen? cheers, Chris MaunderA number of years ago Microsoft published the DefWndProc source code, which is what you call from your WndProc after you have processed a windows message. I believe the function was over 3000 lines of code, although I have seen such long switches in Excel functions, too, but maybe not that long. There was a label called "ICantBelieveIUsedGoto" in the function, that went from one location of the function to another location. What I don't understand is why each case could have been broken out into a separate function, thus making it easier to maintain. Oh, yes, I remember, because this was windows 3.1. Thanks, Wes

I have been programming for 20+ years and never ever found any use for
continueorbreak(except off coursebreakin aswitchstatement), so to answer your question, no, they cannot. The same goes for thereturnstatement. There can be only 1 entry point for a function and only 1 exit point. We always use a local var (result) to set the return value of a function. Using statements likegoto,continue,breakandreturn(the latter used in the wrong place) leads too often to "spaghetti code" IMHO. -

The multiple returns probably 1 in every 2K lines. I have not used a goto in several years so the ratio will probably be like 1 in every 250K lines I write... John

Using statements likegoto,continue,breakandreturn(the latter used in the wrong place) leads too often to "spaghetti code" IMHO.There are definitely times when using continue, break, and return is actually better than not doing so. But when you find yourself needing to do it, it's important to ask yourself if there is a better way - breaking the function up into multiple functions, etc. If you say absolutely no gotos/continues/etc, occasionally you'll run into a place where in order to go by your rules you'll have to produce code that's more like 'spaghetti code' than if you allowed its use. * Believe me - I've seen this before (not very often, though). *Most of the cases were in complex string parsing functions.

I do remember coming across a Microsoft VC++ sample that used goto - if I'm not mistaken it was one of the multimedia samples.My 20 favorite films:

gotokeyword you've seen? cheers, Chris MaunderANd now, for something completely different... I am currently contemplating sticking a *bunch* of gotos in my next component. It's C, it's an authentication component, and therefore its logic is something like: IF (bad user id) { error=BAD_ID; skip the rest except the last piece; } IF (bad PSW) { error=BAD_PSW; skip the rest except the last piece; } ... last piece: record to log file/DB what happened; return Success/Failure So.. a *big bunch* of nested if's, or a *big bunch* of if-else's, or a *big bunch* of gotos Aside, if no-one notices, I'm sure tempteds to use the gotos just 'cause ! I'd stop only if it would lead to the problems I hit in Assembly, when the label is too far, but I have never seen that problem in C/C++. Geee... they gave use a goto statement... let's use when appropriate ! F.O.R.
