because that's how the "IF (expression)" command syntax works..
you should en-close the expression in parenthesis (or round brackets, however you wanna call 'em) unless...
look here

ok the problem is how i'm assigning the variable
apparently quotes throw everything off
can someone explain this to me? i'm using the assignment operator
http://www.autohotkey.com/docs/commands/SetExpression.htm
| Code: |
ss := "hi"
f1::
msgbox %hi% ; hi as expected
if ss=hi
msgbox this works
if (ss=hi)
msgbox this doesnt
return
|
| Code: |
ss := hi
f1::
msgbox %hi% ; empty wtf
if ss=hi
msgbox this doesnt
if (ss=hi)
msgbox this works
return
|
whats going on here? what is getting stored in the 2nd example? |

No, it is not.
| Code: | Loop, Parse, mylist, `,
{
if move = hello
msgbox zxzcvzxvcz
if (move = "hello") { ; notice the quotes around LITERAL TEXT IN AN EPRESSION
msgbox qwerqwer
;more code..
}

An explanation and many examples are provided here: AutoHotkey Expression Examples: "" %% () and all that . Section H expressly applies to your mis-understanding. |
