</div>

var myConstant:Number = 3  
for (var i:int = 0; i \< 30; i++)  
{  
switch (true)  
{  
case i \> 20:  
trace(i,"\>20");  
case i % myConstant == 0:  
trace(i,i % myConstant == 0,i % myConstant);  
default:  
}  
}

why does it suddenly start tracing ‘false’ after 20???  
weird

Because you forgot a `break` statement before your second case.

[QUOTE=Krilnon;2663074]Because you forgot a `break` statement before your second case.[/QUOTE]

actually, it took the breaks out to test if for every “i” it indeed would execute all cases it actually matches (so if it matches more then 1 of the possible cases)

it does but it also starts suddenly executing/matching the false cases
