Confusion over number assignment

Recommended Posts

Hi, relatively new to AutoIt but has done some programming prior to learning AutoIt.

Got stumped by this statement during my code review of a previous worker's AutoIt script.

Normally, as with all other previous programming languages, this statement seems simple enough:

$hPopup = MsgBox($MB_SYSTEMMODAL, "Title 1", "Insert text here")

But what made me confused is, how does the following make sense?

If 6 = MsgBox($MB_TOPMOST + 68, "Title 2", "Insert more text here") Then
How is it possible to assignment to a fixed number (6) with a call to a function? Shouldn't it be assigning to a variable?
When I ran that script, it could run without compile errors.
I have touched things like Javascript, C# and C++ before, and from past experiences, I am surprised how in AutoIt this script seems syntactically correct.
Can anyone please enlighten me on this?

In AutoIt "=" is not always an assignment operator, the interpreter knows it's a comparison.


In other words it's a very loosely typed scripting language.

Hi JohnOne,

I am actually aware that within the If statement for Autoit, = can be used to test for equality instead of assignment.

But what I think I got into confusion is that I might be more used to seeing this format for comparing:

variable_name [comparing_operator] value_or_variable

as opposed to what I am seeing:

fixed_value [comparing_operator] variable

Does that mean that in AutoIt, the order of how the variables/values are placed is loose too?

In answer to your question, the answer is yes, it doesn't matter which side of the comparison operator you have them. 

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.
