Even though SCAN is enum, the scan task finds the # of seconds (which it uses to delay between cycles) from the menu ASCII name using strtod (see 17.3.1 of the App Dev Guide).  This is unusual.  It would be nicer if menuScan.dbd had 3 fields for every option - the enum value (index number), the user-friendly name, and the "raw" name which is used by the scan task.  But this is a change to epics base and probably not worth the effort.
