If NOT

[legend]

Hello, what is the reason this short code isn't work?

$test = "15"

if not $test = "1" Then
MsgBox("","","test is not : 1")
Else
EndIf

I could use: > <, bigger than or smaller than, but I'd like to use if not.

[mikell]

Because

$test = "15"

if not ($test = "1") Then
MsgBox("","","test is not : 1")
Else
EndIf

[kylomas]

Try it like this

$test = "15"

if not ($test = "1") Then
MsgBox("","","test is not : 1")
Else
EndIf

[mikell]

Maybe kylomas answer is better than mine, may be (not)

[legend]

that worked, sorry for this stupid question, but why does it need : ( )

[Belini]

@legend see if that helps.

$test = "15"

If not ($test = "1") Then
    MsgBox("", "", "test is not = 1")
Else
    MsgBox("", "", "test is = 1")
EndIf

$test = Random(0, 10, 1)
MsgBox("", "", "Number drawn = " & $test)

If $test > 5 Then
    MsgBox("", "", "test is greater than 5")
ElseIf $test < 5 Then
    MsgBox("", "", "Test is less than 5")
Else
    MsgBox("", "", "test is equal to 5")
EndIf

$test = Random(1, 4, 1)
MsgBox("", "", "Number drawn = " & $test)

Switch $test
    Case 1
        MsgBox("", "", "test is = 1")
    Case 2
        MsgBox("", "", "test is = 2")
    Case 3
        MsgBox("", "", "test is = 3")
    Case 4
        MsgBox("", "", "test is = 4")
EndSwitch

The answer is in the helpfile, see 'operators'

'not' checks a true/false logical operation, so you could get the same result using

if not Execute($test = "1") Then ...

Because you're evaluating a literal string and not a numerical value?

Correct answer is because operator NOT has higher precedence than operator =.

Because it checks whether or not $test is true before evaluating whether $test = "1", putting it in parentheses forces the comparison of $test = "1" to determine if that part is true, if ($test = "1") then it's true, so using Not checks to see if it's false

Maybe I just type slower..

Correct answer is because operator NOT has higher precedence than operator =.

Meaning "Not $test" will be interpreted as "false" and "1" will be interpreted as "true" so what you have written is "If False = True".

Right?

[kylomas]

No, it is because

if not $test = 1

evaluates $test for true or false then tests that result against 1, whereas,

if not ($test = 1)

evaluates the entire expression

edit: without knowing the value of $test you do not know what it will evaluate to

edit2: so far we've said the same thing three different ways...

Understood !

$test = false
If not not not $test = true Then MsgBox("","", not not not $test)

[kylomas]

Or

$test = false
If not not not $test  Then MsgBox("","", not not not $test)

*sigh*...long boring afternoon...
