I never understood the religious cruzification of Goto.

Sometimes I do things like:

If anyvar = Null then
   Goto EndAndExit
Endif

'Some or a lot of code ...
'Inside another break:

If anothervar = Null Then
   Goto EndAndExit
Endif


EndAndExit:
End

For that situations I find Goto very useful.

If I use Goto, I only use it to jump downwards. I for me found out that
jumping upwards is a jump to hell.

And if it is really useful (jumping upwards, very very seldom) then it
has to be heavily documented.


Alles Gute
