Can you have a Function inside a Function?

[GoogleDude]

Kinda like below!

Call("MainFunction")

Func MainFunction()
    Call("SubFunction")
    
    Func SubFunction()
        MsgBox(1024,"Test","This is a test!")
        Exit
    EndFunc
EndFunc

Thanks,

No... but you can call other functions from within a function.

[erezlevi]

yes, but you should write it like this: and you can also return parameters if you define them. and don't put Exit anywhere except the mainfunction or in a IF statement or check.

Call("MainFunction")

Func MainFunction()

Call("SubFunction")

MsgBox (0,"end:","")

EndFunc

Func SubFunction()

MsgBox(1024,"Test","This is a test!")

EndFunc

Only shouldn't be using the Call() statement in these cases

MainFunction()
;
Func MainFunction()
    SubFunction()
    MsgBox(0, "end:", "")
EndFunc  ;==>MainFunction
;
Func SubFunction()
    MsgBox(1024, "Test", "This is a test!")
EndFunc  ;==>SubFunction

No. Your example doesn't show a nested function. It does prove what I stated. And, of course, Jos is correct (call is not necessary). Also, I think it's good practice to "run" another function conditionally from within a function (unless it's for organization purposes) but try not to run a function, which runs another function... which runs another function.

is there any way to have the script return to the first function where it left off after running the second function? muttley

Have you found a way to stop it doing that then?

No kidding, I had to read that 3 or 4 times lol.

I am not looking to simply go back to the top of the first function, I am looking to basically do a GoSub comand but there is not GoSub comand in version 3. muttley

Seems the consensus on the net is that no language (worth it's salt) is using GoSub/GoTo anymore "on purpose".

For your "GoSub/GoTo" call, it's better to create independent functions and call them as needed.

Proper code structuring makes for less errors and better readability for even the coder themselves.

From your last post, it appears your still have not got it.

Experiment, it's a great teacher. Jos's example with more MsgBox()'s (Message Boxes).

MainFunction()
MsgBox(0, "", "Just after where  MainFunction() was called at the start")

Func MainFunction()
    MsgBox(0, "", "Top of Main Function")
    SubFunction()
    MsgBox(0, "", "This is in Main Function() just after the SubFunction() statement")
EndFunc  ;==>MainFunction

Func SubFunction()
    MsgBox(1024, "", "This is from/inside the SubFunction()")
    Return
EndFunc  ;==>SubFunction

As you should be able to see is the function that is called from inside the main function does not go back to the top of the first function which it appears you think it does. It doesn't.

It acts more like a GoSub command, which you want.

The commands in a GoSub block make up the function. And this function (GoSub block) is stored outside of any other functions. It takes it place separately among the other functions you create.

If the SubFunction() command returned to the top of the MainFunction() from where it was called, then the MsgBox(0, "", "Top of Main Function") command would appear a second time after the "This is from/inside the SubFunction()" message.

I hope this clarifies what's happening.

Edit: Added Another MsgBox() now @ 2nd line
