Switch/Case/Default

Switch

The Switch/Case/Default condition expression is evaluated and compared to each case label in turn until a match is found. Subsequent labels will be executed until a break is executed. A default clause will always match. The case expressions do not need to be constants and can be of any type.

Examples

switch($response) {
case "hello":

echo "Hello to you too!";

break;
case "goodbye":

echo "See you later!";
break;
default:

echo "I've no idea what you mean!";
break;
 }

Note, the break statement is required to prevent the execution continuing into the next block.

set v=2;

switch($v) {
case 1:

echo "v is 1";
case 2:

echo "v is 2";
default:

echo "v is not 1 or 2";
break;
 }

Since there is no break at the end of the case 2 code segment, DMScript will continue to execute the code following the “default” clause:

v is 2

v is not 1 or 2

If this is not desired, make sure you include break.
