Select/..Case./.Default

Description

Conditionally run statements.

Select
    Case <expression>
        statement1
        ...
    [Case <expression>
        statement2
        ...]
    [Default
        statementN
        ...]
EndSelect

Parameters

Case <expression>

If the expression is true the following statements up to the next Case or EndSelect statement are executed. If more than one of the Case statements are true, only the first one is executed.

Note - If a Case is lacking a Break then the code will fall through into the next case and execute that and fall through again if theres no break.

Remarks

Select statements may be nested.

The expression can contain the boolean operators of AND, &&, OR, ||, NOT, ! as well as the logical operators <, <=, >, >=, ==, ==, and <> as needed.

Example

Heres an example with all breaks in proper place (Break statement is needed to tell the code to stop or else it wil fall through into the next case that may be what you want though)

$var = 1
 
Select $var
    Case 1
    Case 2
        println("Value is 1 or 2")
	break
    Case 3
        println("Value is 3")
	break
    Case "test"
        println("Value is \"test\"")
	break
    Default
        println("No preceding case was true!")
EndSelect

In the above example: if $var is 1 it will go into Case 1 then fall through into case 2 run the code and break if $var is 2 it will go into Case 2 run the code and break if $var is 3 it will go into Case 3 run the code and break if $var is "test" it will go into Case "test" run the code and break if $var does not match any case at all the code inside Default will be run

This means you can in theory place loads of empty Case statements that you want to all fall through.
