Naming conventions for GoTo labels

Question

How do you name your GoTo labels? I use rarely often so I'm having a hard time finding good names.

Please refrain from the classical 'goto is evil and eat your code alive discussion'

Answer 1

In batch files I often use HELL.

Like:

some_command || GOTO HELL

...

HELL: 

echo "Ouch, Hot!"

Answer 2

My label names almost always fall into one of these patterns:

• Called "restart", for restarting a set of nested loops because a change has invalidated something
• Called "exit" or "return", right before the return statement, and is only there because of a trace statement that logs the return value for debugging
• Has the same name as the boolean variable that it replaces

Answer 3

• "cleanup" if it stand before freeing some previosly allocated resources (or similar kind of 'finally' section work)

Answer 4

In fortran, I use goto for rollbacks, and I normally start from 999 backwards (in fortran, goto labels are only numeric)

    call foo(err)
    if (err /= 0) goto 999

    call bar(err)
    if (err /= 0) goto 998

    call baz(err)
    if (err /= 0) goto 997

    ! everything fine
    error = 0
    return

997 call undo_bar()
998 call undo_foo()
999 error = 1
    return

I also use labels greater than 1000 if for some reason I want to skip the rollback part.

In C and other languages, I would use rollbacknumber (eg. rollback1, rollback2), so it's clear from the label that you are going to rollback. This is basically the only good reason for using goto.
