The docs say: "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." TRUE is an expression, and so can be the subject of a switch statement. > The docs show a single variable and checking the case of that > variable. Admittedly all the examples in the manual use a single variable, but from the first sentence of the switch description: "The switch statement is similar to a series of IF statements on the same expression." ... I think it's reasonable to deduce that the parentheses after switch can contain any legitimate expression. Admittedly, all the examples in the manual use a single variable -- perhaps you might want to submit a Documentation Problem bug report suggesting some more complex examples. Actually, looking at the online manual again, I see several user notes with potential candidates for moving to the manual proper, including one which demonstrates the exact usage that the OP was having problems with.
