Compiler Parsing

[pdaughe]

The following presents a problem particularly when using the Execute statement:

$A = 1
$A = $A +++++- 1
MsgBox (0, "Test", "A = " & $A)

No syntax or run-time error is given.

Interesting, you can have as many mixed up + and - as you want, but throw one * or / in there and it errors.

[J-Paul Mesnage]

$A = 1
$A = $A ++++- 1
$B = 1
$B = Execute("$B ++++- 1")
MsgBox (0, "Test", "A = " & $A & @crlf & "B = " & $B)

Execute produce the same value. So the problem is not related to Execute.
Back to the question Autoit works as parenthesis
$A + (+(+(+(- 1))))
so the result is correct whatever you are surprised of the behavior as I am.
You can find other case as Autoit works as in Polish notation (Jon say it is OK)
