By Design Or.....?

Playing with some code for an AutoIt script generator, I discovered Func/EndFunc appears to have a default value. I forgot to add the Return in a couple of places but it seems as if that is the default anyway.

Global $a
Func1()
MsgBox( 0 , '',$a)
Exit

Func Func1()
    $a = 'This is just a demo'
EndFunc
Either way, if this can be confirmed, it might be an idea to add it to the docs.

I don't understand what you're trying to convey here...?

I think GEOSoft is saying that the function has a return value even though he did not include an explicit "Return" statment.

For example, the following prints zero:

MsgBox(0,"", foo() )

Func foo()
EndFunc

The "feature" has to do with the way AutoIt is designed. Look in the help file for all functions that list "None" as a return value, such as Break(0). If you assign such a function to a varaible, you typically get a value of 1.

I didn't know user functions default to returning 1, but all built-in functions return 1 unless explicity set to return something else, so it doesn't surprise me that a user function would also have the same behavior.

I just didn't understand by his code what he was trying to do. He never caused any visible sign that he was checking the return value of the function. All I see is a global variable, then assigning that variable in the function, and printing the result of it. :whistle:

Er, do you mean user-functions default to 0 and built-in functions default to 1, because that the behavior I got.... :whistle: bug/feature?

It used to be that built-in functions defaulted to zero (for success), but Jon changed this in version 3.0.83

Exactly and it will come in handy. While I'm at it, has anyone figured a way to enter a compiled script at a certain point or function? Same as using switches.

Example (from the command line)

  • myapp.exe /1 Starts my app at Func1()
  • myapp.exe /2 Starts my app at Func2()
Okay, so I guess we can ask for too much. :whistle:

If $CmdLine[0] > 0 And $CmdLine[1] = "/1" Then
  doFirstFunction()
ElseIf $CmdLine[0] > 0 And $CmdLine[1] = "/2"
  doSecondFunction()
EndIf

But you cannot enter code at an arbitrary point since AutoIt lacks the GOTO statement. Also, think of the security implications if you could skip over a validation routine :whistle:

Uhh, yeah. :whistle::angry:
