== Syntax ==
* [[switch]](<expression>);
== Description ==
The switch statement is similar to a series of [[if]] statements on the same expression. In many occasions, you may want to compare the same variable (or expression) with many different values, and execute a different piece of code depending on which value it equals to. This is exactly what the [[switch]] statement is for.

It is important to understand how the [[switch]] statement is executed in order to avoid mistakes. The [[switch]] statement executes line by line (actually, statement by statement). In the beginning, no code is executed. Only when a [[case]] statement is found with a value that matches the value of the switch expression the [[case]] statement(s) will to executed. The parser continues to execute the statements until the end of the [[switch]] block, or the first time it sees a [[break]] statement. If you don't write a [[break]] statement at the end of a [[case]]'s statement list, the parser will go on executing the statements of the following [[case]] (fall-through).

== Example ==
// Returns the number of refines on your top headgear
[[set]](.@refCount, [[getequiprefinerycnt]](EQI_HEAD_TOP));
// Output a message
[[switch]](.@refCount) {
// 0 means no refine yet
[[case]] 0:
[[mes]]("No refine on your top headgear yet?");
[[mes]]("You need to go to the refiner!");
[[break]];

// +1
[[case]] 1:
[[mes]]("Your top headgear is +1!");
[[break]];
// +2
[[case]] 2:
[[mes]]("Your top headgear is +2!");
[[break]];

// +3
[[case]] 3:
[[mes]]("Your top headgear is +3!");
[[break]];

// +4
[[case]] 4:
[[mes]]("Your top headgear is +4!");
// NOTE: no break here means the code from "case 5" will be executed afterwards!

// +5
[[case]] 5:
[[mes]]("Your top headgear is +5!");
[[break]];

// [...]

// This case will be triggered if no other case was triggered yet
[[default]]:
[[mes]]("Your top headgear has upgrades above +5!");
[[break]];
}

== Next Example ==
[[switch]]([[rand]](1,3)) {
[[case]] 1:
[[mes]] "Randomly Selected Number is 1";
[[break]];
[[case]] 2:
[[mes]] "Randomly Selected Number is 2";
[[break]];
[[case]] 3:
[[mes]] "Randomly Selected Number is 3";
[[break]];
}
