Android Question Call the same sub inside a sub ?

[marcick]

Is it doable or can create stack troubles ?
Something like this:

Sub pippo() 

     bla bla ..
     bla bla...
     if .. then pippo

end sub

You can, this is recursion.

I was a bit confusing because:

If sub "sub1" call sub "sub2" then sub2 call "sub3", the end of sub3 return to sub2 and the end of sub2 return to sub1. So there is a stack mechanism.

Now, if "sub1" call itself, does it means that the stack is not updated, right ? And the end of sub1 does not return again to sub1 but to who called sub1 the first time, right ?

When Sub1 calls itself it goes also back to itself !

So the behaviour is not like a GoTo.
I need to look carefully the program flow.
Thanks Klaus, bye

NO !
GoTo doesn't exist in B4A.

You don't need goto command, is useless.
