Question about while loops

[Rynhasautism]

Is there a way to make while loops check the expression after each statement is executed? If not what are some ways to emulate this? Should I just put all the statements into an array then use for in next loop to kind of do the same thing?

@Rynhasautism how about an example of what you're meaning? It sounds like your While expression will change once you have entered the loop, and there are a couple of ways to skin the proverbial cat. But rather than guessing at what you're trying to do, and then crafting an example that would make sense to you, a detailed explanation of what you want the loop to do step by step would be helpful.

like this ?

While 1
    ConsoleWrite("! do the stuff" & @CRLF)
    If Not 1=2 Then ExitLoop
WEnd

If this is what you was looking for (thinking about)..... you should focus on:
 

Do
    ConsoleWrite("! do the stuff" & @CRLF)
Until 1<>2

well a normal while is like 

While Expression() = $valueIWant
    Statement1()
    Statement2()
    Statement3()
WEnd

Where it only checks the expression at the start of the loop. I'm looking to do something like 

Expression() = $valueIWant
Statement1()
Expression() = $valueIWant
Statement2()
Expression() = $valueIWant
Statement3()

Was thinking of something like this at first but it doesn't exit the loop 

While $flag = $flagIWant
Statement1()    
WEnd
Func Statement1()
    Return $flag = Expression()
EndFunc

The for loop thing I was talking about was something like 

$aArray [1][2] = ["function", $parameter]


For $i = 1 To UBound($aArray) - 1
    
    If Expression() = $valueIWant Then 
        Local $FuncName = FuncName($aArray[$i][0])
        call($FuncName, $aArray[$i][1])
    EndIf
Next

Couldn't you turn the logic around and do something like this? --

While 1
    If Expression() <>  $valueIWant Then ExitLoop
    Statement1()
    If Expression() <>  $valueIWant Then ExitLoop
    Statement2()
    If Expression() <>  $valueIWant Then ExitLoop
    Statement3()
WEnd

Yeah lightweight trying to be somewhat efficient and do it in the least amount of instructions possible while avoiding the ctrl+v, ctrl+v,

A switch statement maybe?

While 1
    local $ReturnValue = Expression()
    Switch $ReturnValue
        Case 1
            Statement1()
        Case 2
            Statement2()
        Case 3
            Statement3();
        Case Else
            Exit
    EndSwitch
WEnd
