27 13 Dec 09 GKY Fixed separate paramenters. Please note that appname should be used in
28 profile calls for user settings that work and are setable in more than one
29 miniapp; FM3Str should be used for setting only relavent to FM/2 or that
30 aren't user settable; realappname should be used for setting applicable to
31 one or more miniapp but not to FM/2
