Qustion about Case

[OliverA]

Hello, i'm stunding Case but i have a question, if i have:

Switch $var
Case 1
ConsoleWrite("1")
Case -1
ConsoleWrite("-1")
EndSwitch

How to make a Case if are 1 or -1? Like:

ConsoleWrite("is 1 or -1")

I have test with:

Case -1 or 1

But nothing, some advice?

OliverA,

I agree the Help file syntax example is not too clear - you do it like this:

Case 1, -1

I have test it, but i need to remove the other cases, here work:

Switch $var
Case 1, -1
ConsoleWrite("is 1 or -1")
EndSwitch

But here not:

Switch $var
Case 1
ConsoleWrite("1")
Case -1
ConsoleWrite("-1")
Case 1, -1
ConsoleWrite("is 1 or -1")
EndSwitch

Is always ConsoleWrite("1") or ConsoleWrite("-1")

I'd like the ConsoleWrite("1") and the ConsoleWrite("is 1 or -1")

OliverA,

That is because you only ever only fire a single Case statement - so you will always fire either the 1 or -1 Case before you ever get to the double one.

If you want to discriminate further you have to do something like this:

$var = 1

Switch $var
    Case 1, -1
        ConsoleWrite("is 1 or -1" & @CRLF)
        Switch $var
            Case 1
                ConsoleWrite("is 1" & @CRLF)
            Case -1
                ConsoleWrite("is -1" & @CRLF)
        EndSwitch
EndSwitch

All clear?

Switch selects one of the defined cases. You want it to select two. That's not possible. You need to use multiple if statements:

If $var = 1 Then ConsoleWrite("1")
If $var = -1 Then ConsoleWrite("-1")
If $var = 1 Or $var = -1 Then ConsoleWrite("is 1 or -1")

But do you have a real world example?

[OliverA]

Thanks Melba, your solution is good and do what I tried to do it myself unsuccessfully

Water, a real world example? I want only to understad how to make a case with 2 different result.

We can even remove some more line of code

$var = 1

Switch $var
Case 1, -1
ConsoleWrite("is 1 or -1" & @CRLF)
ConsoleWrite("is " & $var & @CRLF)
EndSwitch
