If And Or

[LuigiBem]

This is not a game.

This guy also wanted to know but I don't see the answer:

 

'?do=embed' frameborder='0' data-embedContent>>

;This works
If $fpath = "..\Quest" Or $wrt[1] = 0 Then $TurnIt = "Nope"


;Why doesn't this
If $fpath = "..\Quest" And $wrt[1] = 0 Then $TurnIt = "Nope"

It's another one of those things not in Help.

So what is your problem as they are 2 different tests?

What are you expecting?

Post something that really shows your issue instead of  a few lines that don't have any meaning.

First example needs only one of the camparisons to be true. For the second example both need to be true.

LuigiBern,

It works for for me:

expandcollapse popup

; Both match
$fPath = "..\Quest"
Global $wrt[2] = [0, 0]
$TurnIt_1 = "Yep!"
$TurnIt_2 = "Yep!"

If $fpath = "..\Quest" Or $wrt[1] = 0 Then $TurnIt_1 = "Nope"
If $fpath = "..\Quest" And $wrt[1] = 0 Then $TurnIt_2 = "Nope"

ConsoleWrite("Both match: " & $TurnIt_1 & " - " & $TurnIt_2 & @CRLF)

; Path matches
$fPath = "..\Quest"
Global $wrt[2] = [0, 1]
$TurnIt_1 = "Yep!"
$TurnIt_2 = "Yep!"

If $fpath = "..\Quest" Or $wrt[1] = 0 Then $TurnIt_1 = "Nope"
If $fpath = "..\Quest" And $wrt[1] = 0 Then $TurnIt_2 = "Nope"

ConsoleWrite("Path matches: " & $TurnIt_1 & " - " & $TurnIt_2 & @CRLF)

; wrt matches
$fPath = "..\Quest0"
Global $wrt[2] = [0, 0]
$TurnIt_1 = "Yep!"
$TurnIt_2 = "Yep!"

If $fpath = "..\Quest" Or $wrt[1] = 0 Then $TurnIt_1 = "Nope"
If $fpath = "..\Quest" And $wrt[1] = 0 Then $TurnIt_2 = "Nope"

ConsoleWrite("wrt matches: " & $TurnIt_1 & " - " & $TurnIt_2 & @CRLF)

; Neither match
$fPath = "..\Quest0"
Global $wrt[2] = [0, 1]
$TurnIt_1 = "Yep!"
$TurnIt_2 = "Yep!"

If $fpath = "..\Quest" Or $wrt[1] = 0 Then $TurnIt_1 = "Nope"
If $fpath = "..\Quest" And $wrt[1] = 0 Then $TurnIt_2 = "Nope"

ConsoleWrite("Neither match: " & $TurnIt_1 & " - " & $TurnIt_2 & @CRLF)

Why do you think it does not?

I will not refute my ingnorance here. I have no idea how this works. I expected the "And" to work the same as the "Or". I was hoping I could use the "Nope" as a variable later, but the script terminates.

The conditions match but the MsgBox comes back empty.

MsgBox(0, "$fpath", $fpath) ;This tests "..\Quest"
MsgBox(0, $wrt[1], $wrt[1]) ;This "0"
If $fpath = "..\Quest" And $wrt[1] = 0 Then $TurnIt = "Nope"
MsgBox(0, $TurnIt, $TurnIt)

I've tried all combinations of quotes: ($fpath = "..Quest") And ( the like...

I expected the "And" to work the same as the "Or".

Why should it work the same way?

If you have a glass of beer AND a cup of coffe you have two beverages.

If you have a glass of beer OR a cup of coffe you have at least one beverage.

So And <> OR.

LuigiBem.

Once again it works fine for me:

$fPath = "..\Quest"
Global $wrt[2] = [0, 0]
$TurnIt = "Yep!"

MsgBox(0, "$fpath", $fpath) ;This tests "..\Quest"
MsgBox(0, $wrt[1], $wrt[1]) ;This "0"
If $fpath = "..\Quest" And $wrt[1] = 0 Then $TurnIt = "Nope"
MsgBox(0, $TurnIt, $TurnIt)

I would recommend declaring $TurnIt before trying to access it as I have done above.

My mistake. I expected it to work similar.  The "Or" continues on.  The "And" Terminates the Script.  The conditions seem to be met for both,  as far as I can tell, yet they are not working similarly as I see it.  I don't understand why $TurnIt does not fill the MsgBox with "Nope".

[Melba23]

LuigiBem,

 

I don't understand why $TurnIt does not fill the MsgBox with "Nope".

Do you not see "Nope" when you run the script I posted immediately above?

 

The "Or" continues on. The "And" Terminates the Script

Not exactly. What happens is this:

; Here is the line with And
If condition_1 And condition_2 Then

; And needs both conditions to be true or it fails
If True And True Then   ; Both true and it works
If False And True Then  ; One false and it does not work - in fact AutoIt never even looks at the second condition
If True And False Then  ; One false and it does not work
If False And False Then ; Both false and it does not work - again AutoIt never even looks at the second condition

; Here is the line with Or
If condition_1 Or condition_2 Then

; Or needs only one of the two conditions to be true
If True And True Then   ; Both true and it works - AutoIt does not even look at the second condition
If False And True Then  ; One true and it works
If True And False Then  ; One true and it works - again AutoIt does not even look at the second condition
If False And False Then ; Both false and it does not work

I hope that makes it clearer.

$fPath = "..\Quest"

It turned out $fpath had a bug upstream which had caused me to question the difference between "And" & "Or".

You have made it very clear that I needed to look elsewhere for the bug.

Thank you very much for the explanation And Or understanding to resolve this issue.

[SadBunny]

Why should it work the same way?

If you have a glass of beer AND a cup of coffe you have two beverages.

If you have a glass of beer OR a cup of coffe you only have one beverage.

So And <> OR.

 

Not exactly true... If you have a glass of beer OR a cup of coffee, all you know is that you didn't have no beverage.

[water]

Ops, you are correct.

Should be "at least one beverage" Somehow I had "Exclusive Or" in mind.

Fixed.
