Does Not Equal Command?

[ravenfyre]

We all know about "If something = something then" but what about "If something ≠ something then"? Didn't find any help on any does not equal command in the autoit help file, does something like this exist? If not is there any way around this, maybe using <> instead of ≠ which I know doesnt' work ?

$x=4
if $x=3 then
else
msgbox(1,"it worked","$x="&$x)
endif

if $x<>3 then msgbox(1,"it worked again","$x="&$x&" not 3")

If $x <> $y

If Not ($x = $y)

If Not ($x == $y)

Note that == is a case-sensitive comparison while = is case-insensitive.

If Not ($x = $y)

Interesting, I always thought that "=" was assignment, and "==" was comparison...

Then again "!=" doesn't seem to work in AutoIt, so I have no clue what to think.

Instead of using !=, use <>. You could also do something like (untested):

$x=6

If Not $x = 5 Then

MsgBox(0,"Test","$x isn't equal to 5.")

Else

MsgBox(0,"Test","$x is equal to 5.")

EndIf

Instead of using !=, use <>...

Thanks for advice... Though, I was joking when I made the comment about "!=".

(Hmm, there needs to be a :shrug: emoticon here)

$x=6

If Not $x = 5 Then

  MsgBox(0,"Test","$x isn't equal to 5.")

Else

  MsgBox(0,"Test","$x is equal to 5.")

EndIf

$x=6

If Not($x = 5) Then
  MsgBox(0,"Test","$x isn't equal to 5.")
Else
  MsgBox(0,"Test","$x is equal to 5.")
EndIf

Need to have the parenthesis around the condition being evaluated for NOT to work properly.

Hmmm. It seems to have worked fine for me in the past without the parens. Thanks for letting me know.

I think Jon updated the order of operations in one beta.

The precedence of operations, from highest to lowest:

    ( )

    NOT

    ^

    * /

    + -

    &

    < > <= >= = <> ==

    AND OR

Thus, Not $x = $y evaluates as (Not $x) = $y
