If you end up here it means you specifically used an event that was in the
unsupported list...NAUGHTY!
1 when pos(event,notsupported) > 0 then do
2 lister set handle busy on
3 call displayerror(getcatstr(23,'Command not supported in ArcDir.'))
4 lister set handle busy off
5 end
Line:
1 Compare the event against the list of not supported commands set back
here .
2 Set the lister state to busy.
3 Get the displayerror routine to...eerr...display an error message,
translating if necessary through getcatstr .
4 Set the lister back to idle state.
5 End of the When loop.
