OMG a "Goto"
-
I like this reason as well void foobar() { // blah blah blah for(...) { // blablabla for(..) { // foo foo foo if(bar) goto end; } } end: // beep bop a loola }
A train station is where the train stops. A bus station is where the bus stops. On my desk, I have a work station.... _________________________________________________________ My programs never have bugs, they just develop random features.
Even Java has the "goto" similarity where you can "continue" to a label.

I've programmed for over 10 years. The old BASIC, like GW-Basic or BasicA, yes I can honestly say that goto came in handy. However, I never once used it in C,C++, VB.NET or C#. Never. Since all modern languages have a Continue statement and a Break statement (for loops), I never needed a use for a goto. The reason, I'm guessing, that its not being removed in modern languages is to keep it compatible with old code. Very rarely does a language "lose" a command. They keep them so old code is compatible.

try it! you will improve you C# knowledge! or maybe read better... it's a double nested loop

It's an understatement to say that "goto came in handy" in the old style BASIC. You had to use
GOTObecause the language was severely lacking in control flow.DO...LOOPdidn't exist, so you had to make those loops withGOTO.SELECT CASEdidn't exist, so you had to useON...GOTO. Multi-lineIFstatements didn't exist, so you either had to cram everything on one line or useGOTO. And exceptions didn't exist, so you usedON ERROR GOTO. So you ended up with code like this, filled withGOTO. And furthermore, line numbers were mandatory on every line, so it was very difficult to tell which lines wereGOTOtargets and which weren't. And this is what caused all the animosity towards theGOTOstatement. -

LMAO!!!! Didn't release it even existed in c#!! Love it! That will show those annoying OO purest with their fancy classes and methods and thingies!! :laugh: Go the GOTO!

in C++ drop throw switch-statement is allowed in C# not - if it was that, you didn't see.

You may throw an exception for that. :)

[My articles]hmm, what do you think? Why is the name of the Exception object "Exception" - because you should (ab)use it for control program flow? So I see it like this: Use Exceptions for exceptions Avoid goto, but if you must, why not use goto? A single goto, for a purpose as shown above, for shure does not leed to spaghetti-code, but don't try to replace all your for/whiles... with a goto. ;P

I know. But in the pseudocode above it will definitely execute the 'beep bop a loola'... :-D Regards Thomas
wrong! read the code!
