select case

The syntax for the select command is:

select <expression>

case <expression>

[statements]

case <expression1> to <expression2>

[statements]

case is <comparison operator> <expression>

[statements]

else

[statements]

endselect

When no case expressions match, the else statements are executed.

When more than one case expression matches, only the first matching block will be executed.

Control then passes to the instruction following the endselect command.

An example:

a = 4

select a

case 4

LedRed = on

case is > 3

LedGreen = on

case 1 to 7

LedBlue = on

endselect

Here, all three case expressions match, but only the Red LED will light up.

a = 4

select a

case 5

LedRed = on

case 1 to 3

LedGreen = on

else

LedBlue = on

endselect

Here, none of the case expressions match, so "else" bock will execute (the Blue LED lights up).
