Are we really listing all the ways it doesnt work?  Instead of acknowledging that I aced an answer to Post #1 at slot #13, yall had nothing but bloviating about safety.  Im about to include the scope creep at #16 ftw too.

I just wanted to report more cases of errors
want you to fix or someone will write a new code to work.

GetTheVariableNameOfThis(StringSplit("word", ""))

Func GetTheVariableNameOfThis($Value)
    MsgBox(0,0, VarGetType($Value))
Endfunc

 

It is to get types, not the name of the variable.

This can certainly be done, but the methods to do it may fall foul of forum rules and I believe terms of usage. However, a program can be designed which monitors its own behaviour without contravening these terms/rules. Here is an example which monitors itself as it passes a random global variable to the function WhatIs(). It has limited application. In this simple case, the calls to Random() could have been monitored more easily: instead of testing the variable name. This comparison may not work for all data types.

#include <AutoItConstants.au3>

Global $g__aGlobalVariables = ['g__It_Is_Me', 'g__Now_It_Is_Me'] ; global variable names are added to this array [do not include constants]
Global $g__It_Is_Me = 0, $g__Now_It_Is_Me = 1

For $i = 1 To 10
    ; send a random global variable to a function
    If Random(0, 1, 1) Then
        ConsoleWrite('$' & WhatIs($g__It_Is_Me) & @LF)
    Else
        ConsoleWrite('$' & WhatIs($g__Now_It_Is_Me) & @LF)
    EndIf
Next

Func WhatIs(ByRef $vAnyGlobalVariable) ; ByRef must always be used for this method to work (also by all calling functions)
    Local $vTemp = $vAnyGlobalVariable
    For $i = 0 To UBound($g__aGlobalVariables) -1 ; loop through the list of variables
        If IsDeclared($g__aGlobalVariables[$i]) = $DECLARED_GLOBAL And $vAnyGlobalVariable == Eval($g__aGlobalVariables[$i]) Then
            If Assign($g__aGlobalVariables[$i], Not $vAnyGlobalVariable, $ASSIGN_EXISTFAIL) = 1 Then
                If $vAnyGlobalVariable <> $vTemp Then
                    $vAnyGlobalVariable = $vTemp
                    Return $g__aGlobalVariables[$i]
                EndIf
                Assign($g__aGlobalVariables[$i], $vTemp, $ASSIGN_EXISTFAIL)
            EndIf
        EndIf
    Next

    Return SetError(1) ; don't know what it is!
EndFunc

I'm showing that you cannot get the name of a variable passed to a function if that variable is anonymous.

All these pointless scripts to do something the OP has already demonstrated how to do it in his first post? The easiest way is to write the script to do what you want when you write it. There's no built-in way to do it, and any other method is WAY overkill, especially when the way demonstrated already is the simplest way to do it.

just wanted to see if it was possible to do it another way.

thanks =)
