About a return command

[youtuber]

2 writes and how returning?

$var1 = "1.variable"
$var2 = "2.variable"
$var3 = "3.variable"

For $i = 1 To 3 Step 1
MsgBox(0,"test Message header",$var1)
Next

For $i = 1 To 3 Step 1
MsgBox(0,"test Message header",$var2)
Next

If ($var2 = 2) Then Return $var1

For $i = 1 To 3 Step 1
MsgBox(0,"test Message header",$var3)
Next

@youtuber you use Return to exit a function with the desired value. I'm not sure what you're trying to do from your code, but a typical return would be something like this:

#include <MsgBoxConstants.au3>

MsgBox($MB_OK, "Example", Example(8))


Func Example($iVal)
    Local $x = 0

    Switch $iVal
        Case 4
            $x = "Four"
        Case 8
            $x = "Eight"
        Case 12
            $x = "Twelve"
    EndSwitch

    Return "You chose the number " & $x
EndFunc

@JLogan3o13 Thank you 

I understand better now thanks to the return command

then how can I get value if?

#include <MsgBoxConstants.au3>

MsgBox($MB_OK, "Example", Example(8))

If Example = 4 Then
    MsgBox(0,"test","Example 4")
ElseIf Example = 8 Then
        MsgBox(0,"test","Example 8")
ElseIf Example = 12 Then
        MsgBox(0,"test","Example 12")
EndIf

Func Example($iVal)
    Local $x = 0

    Switch $iVal
        Case 4
            $x = "Four"
        Case 8
            $x = "Eight"
        Case 12
            $x = "Twelve"
    EndSwitch

    Return "You chose the number " & $x
EndFunc

I still don't understand what you're trying to do. The String returned from the function will be "You chose the number" and then the string representation of whatever number you pass to the function. So Example is never going to = 4 or 8. You need to explain in detail what you're trying to accomplish, as you aren't being very clear.

I want to do something like

If Example = 4 Then
Run("notepad.exe")
else
Run("mspaint.exe")

So something like this:

ShellExecute(Example(12))

Func Example($iVal)
    Local $sApp

    Switch $iVal
        Case 4
            $sApp = "notepad.exe"
        Case 8
            $sApp = "mspaint.exe"
        Case 12
            $sApp = "calc.exe"
    EndSwitch

    Return $sApp
EndFunc

 

[youtuber]

yes you can show this, but I want to return with an if statement

Can you show me an example of the if statement thank you

[Synapsee]

#include <MsgBoxConstants.au3>

$test = Example(12)
Switch $test
    Case "qsdsqdqsdqsd.exe"
        ;...
    Case Else
        MsgBox(0,"test","Example " & $test)
EndSwitch

Func Example($iVal)
    Local $sApp

    Switch $iVal
        Case 4
            $sApp = "notepad.exe"
        Case 8
            $sApp = "mspaint.exe"
        Case 12
            $sApp = "calc.exe"
    EndSwitch

    MsgBox($MB_OK, "Example", $iVal)

    Return $sApp
EndFunc
