Simple Question for most

[Varian]

What is the difference when you use 2 equal signs? (a== b instead of a= Also, I have seen this in several scripts (&=). What does that mean? If you have any links or ideas that give me more info, please send them as they would be greatly appreciated. TIA.

"==" means an exact match

If "abc" = "ABC" then ; TRUE

If "abc" == "aBc" then ; FALSE

&= is like equals this AND this:

$test = "He"

$test &= "y"

$test now equals "Hey"

Yep. =& is a shortcut with concatenation, that confused me for a while too.

Another way to write what he wrote about would be

$test = "He" & "y"

&= is just writing it shorter.

Sort of like how you can increment with +=

Also look at Language reference -> Operators in the help file..

= equal to

== exact match

> greater then

< less then

<> not equal to

I second that. I was literally was able to teach myself how to code autoit (less the complex stuff) with just the help file and the abundance of example scripts.

I have never seen a help file as neat and usefull as autoit.

Try learning VB, those help files are a mess and dont usually give a full example of working code to test and see how and what its doing.
