AutoIt v3.3.11.3 Beta

[trancexx]

What exactly you see there that it makes you think it's a bug? "Doesn't work" means what?

[JohnOne]

syntax error, single line if. missing Then.

[trancexx]

Is this about Au3Check tool, AutoIt language or interpreter issue?

[UEZ]

Using this code I'm getting an error message:

#AutoIt3Wrapper_Run_AU3Check=n
$a = 2
$b = 1
If ($a > 1) Then ($b *= -1)
ConsoleWrite($b & @LF)

"C:test07.au3" (4) : ==> Missing right bracket ')' in expression.:

If ($a > 1) Then ($b *= -1)

If ($a > 1) Then ^ ERROR

For $a = 1 it works w/o an em.

it consider it like func i guess

func Then($b *= -1)

endfunc

That is correct error message. What confuses you, I guess, is that the error is detected at runtime.

Interpreter will check the syntax of your code to a certain degree before it starts executing it, but obviously it wouldn't check whether you are trying to sell compound operators under something else.

For case when $a = 1 there are no run-time errors - because there are no run-time errors.

For me the stuff in brackets will be executed first then outside the brackets.

I would expect that for If ($a > 1) Then ($b *= -1) $b will be set to -1 as it will be done without brackets.

your calling func Then() starting with If with no Then after func

and Then cant be func name conflict of interest i guess

Which function?

Function named "Then()" that cant exsist coz Then cant be Func.

My 2 cents worth:

This sentence in the help file for Operators describes what you see: "You can use brackets to force a part of the expression to be evaluated first."

So first the expressions in the brackets are evaluated. Means

($a > 1) evaluates to True

($b *= -1) returns the error

 

If you try:

If ($a > 1) Then ($b = -1)

$b still will not be -1 because the expression in brackets is not an assignment but a comparison. Edited January 23, 2014 by water

If <expression> Then statement

When I created this code >here I wrote accidently If ($x > 200) Then ($iDir *= -1) which caused the error.

I just asked my self whether I've some logical problem to undersand why the statement in brackets is not executed as without brackets...

_GUICtrlListView_CreateArray - useful thing to add.

Compound assignment operators modify the value of a variable by performing an operation on it, they don't return value.

When you put expression in parentheses you ask for its value:

$x = 3
$b = 2
($b = -1)

ConsoleWrite($b & @CRLF)

...That code is equivalent to:

$x = 3
$b = 2
(False)

ConsoleWrite($b & @CRLF)

Your $iDir *= -1 doesn't yield value and therefore can't be enclosed in parentheses.

Some languages work differently.

[Richard Robertson]

I thought everyone already understood that we can't wrap statements in parenthesis?

[water]

Obviously not

[Inververs]

I think AutoIT needs explicit assignment operator, such as := or ===

Don't be shy, explain why you think what you do.

[Richard Robertson]

Many languages allow assignment mid expression, however assignment takes = and equality comparison takes == in those languages.
