Do you use goto?

[MrSeanKon]

What's your opinion gizmo???
As you see in OcBible source code I use it sometimes.

[Gizmo]

I've yet to find a situation in any language other than assembly where a goto statement was used that I couldn't rewrite without a goto.

I find that the goto statement tends to create clutter and cause problems with logic that you wouldn't have otherwise. In addition, handling goto is a major PITA for compilers, because you have to keep track of how many nesting levels you have and things of that nature.

[MrSeanKon]

goto is more common in FORTRAN.
Do you use it??
Only in the first year (when I was student) LOL....

[Gizmo]

It's been 25 years since I've written anything in Fortran. Even then, I tended to avoid goto.

Really, assembly is the only place where I commonly use goto (usually called jump), and that has more to do with the restrictions inherent in the way you have to write assembly than anything else.

[MrSeanKon]

Usually I use goto when I want to jump from a nested loop outside cos break does not do this.

When I worked as a programmer, use of "goto" was banned.

Jumping out of a loop, is very bad practice.

What I might do was create a variable called, say, error_code. Set it to 0 by default, then test it as part of your loop logic.

In English:

While whatever and error_code equals 0, then do
open a file and read it, else error_code = 1
Repeat the do loop

If error_code equals 1 then display message about being unable to open the file, else display message saying process completed.

Something along those lines!

If it is nested, then so long as you are always testing error_code in each nest, then all loops will exit if error_code is something other than 0.

[Gizmo]

I do something very similar, except I generally just set a boolean var. If it is true, then I want to exit the loop. If I have two different loops, and the outer loop needs to run even if the inner loop exits early (or needs to exit under its own conditions) then I may have several different booleans for the purpose, but it is the same idea.

[danrok]

Yes, now after dusting my memory, used a boolean as well, and had another variable for specifying the type of error (if needed).

[MrSeanKon]

Thanks!
It is an acronym!

[chrisbard]

Gotcha I can be a major PITA sometimes !

[MrSeanKon]

LEET!
I can imagine why........

[Daniel ~]

A more common English usage would be Pain In The Ass. As such The bard serves as a sterling example! ":O}

[chrisbard]

Sheesh Dan why didn't you just give the short explanation?

[Samuknow]

I think you were the short explanation.....

[chrisbard]

Shuddup Sam what are you, his lawyer?

It's even more common in batch

[Favu]

And most common in infinite loops.

Not that I have ever sabotaged a computer museum exhibit in such a fashion.

Honest officer.
