You can always hack the compiler/bytecode to be able to have gotos wherever
you want, but I think Gotos is not allowed to jump into control structures
because it is classed as "bad code structure". For ... Next also use hidden
local variables to store things.
But I think gosubs can be implemented
I made quick effort to try to simulate gosub with goto,
and noticed that jumping back inside loops is not possible (as the
documentation says...).
I understand that when it's For ... Next, but shouldn't that be possible
with Do ... Loop Until x?
Anyway, I'm not sure my simulation does accurately
GOTO is not evil, but can, if you do it "wrong", result in code that might
be hard to read.
For example, in C you can do like this:
if (a){
goto a_label;
} else {
if (b){
switch(c){
case 1: puts("Hello"); break;
case 2: puts("Yo"); break;
a_label: puts("Tjena"); brea
I red somewhere that GOTO is something that a good programer should
avoid at all costs.
GOTO is a host of countless bug possibilities.

Benoit,
I came across the need to call many different common small pieces of code
multiple times.
Naturally, we tend to make a SUB just for all of them.
I wondered if you'd consider resurrecting GOSUB {label}
which is in the same sub.
It would be in the same scope, no parameters allowed and
act
