strswitch in Igor Pro

The same shape for strings — and note it still closes with endswitch.

Function Apply(String action)
    Variable code = -1

    strswitch (action)
        case "clear":
            code = 0
            break
        case "reset":
            code = 1
            break
        default:
            Print "unknown action:", action
    endswitch

    return code
End

How it works

1. strswitch compares strings, case-insensitively by default.
2. It closes with endswitch; there is no endstrswitch.
3. break leaves the switch, so a case that returns needs no break.
