switch

Description

This function acts like the switch statement in C-like programming languages. It takes the value argument and compares it to each of the case1 through caseN expressions. If value is equal to caseX , then switch returns valueX . If value is not equal to any of the case1..N , then returnDefault is returned.

Note that switch() is similar in functionality to the case() expression function . The difference between the two is the order in which the parameters are passed.

Syntax

switch( value, case1, ...caseN, return1, ...returnN, returnDefault )

Examples

//The following would return 46 because the value (15) matched case 3, so the third return (46) was returned.
switch(
15, // value
1,  // case 1
24, // case 2
15, // case 3
44, // return 1
45, // return 2
46, // return 3
-1) // default

 //The following would return "Running".
switch(
1, // value
0, 1, 2, // cases 1-3
"Off", // return 1
"Running", // return 2
"Fault", // return 3
forceQuality("!BAD STATE!",0)) // default
