do you use goto? [modified]

Hey guys, My former team mate used goto's quite often (to my despair). I just published a small post on when to (not) use goto on my blog[^] where I try to look at this in a pragmatic way. I am interested if you are using goto's (or know someone who does?). Opinions? cheers, Pakl PS: This is just a blunt advertisment for my blog so I can lure you into it and become rich and famous. :-\

Again, not really. I've encountered situations (even recently) where I felt that a few goto statements will save me from writing a buttload of ugly nested if-if-if statements.

The only time I've ever used goto was in the QBasic days, and in Visual Basic when I was first learning that language. I've never used it in any C flavor language, and never allow it when doing code reviews at work.

under any circumstance use goto I use the following
#define BeamMeUp(_goto) goto _goto int AtPlanet() { bool bToDangerous = true; if(bToDangerous) BeamMeUp(scotty); else Fight(); scotty: return ToEnterprise(); }

I use
label:
…goto label
whenever I have to usewhile (true) {
…}

I have less than 5 gotos in the 500K+ lines of code I have written in the last 10 years so its quite rare for me.

I haven't used a goto in 25 years of programming, but I like the option to be available in case I need it. It's been claimed that a goto is useful for exiting deeply-nested code when an error is detected. But in the evolution of my programming style, my methods have become much shorter and only rarely have deep nesting. I can only think of two occasions a goto was necessary. One was when I encountered a bug in IBM's PL/I compiler back in the 1980s, and I needed a goto to force sequential execution. (The next statement wasn't being executed.) The other time was in grad school in the 1990s when I was implementing a system that translated a flow graph drawn on the screen into C code. Each mechanism (a box on the screen representing a library component) was assigned a label, and gotos were part of the automatically-generated template for sequencing their execution. A goto would also be useful for a rapid fix under time pressure. It's good that gotos are discouraged. They're easy and the temptation to use them is great for that reason. (I used them constantly in BASIC when I first learned to program.) But code is already complex enough without making it more complex with abrupt changes in flow.

I haven't used a GOTO in a long time, though it was perfectly natural to use it when there was little else available. Considering that I started with JP, JZ, JNZ, etc, GOTO seemed a logical next step. Now that modern languages include so many more functional constructs, it would be difficult to find a reason for using GOTO. I suspect that, if the need existed, it would be due to timing/memory constraints and I'd be smarter to go back to Assembly code to optimize the routine. That being said, I don't consider the use of GOTO bad form, if it's appropriate to the problem at hand - a state machine implementation, for instance.
