I want the two components shown partially below to have a pointer to the
other. For some reason, I keep getting "Not an allowed type". Why?
Thanks for your help.

You have the asterik in the wrong place. It should be this instead:
__property TtmCalendar* Calendar = {write=FCalendar, read=FCalendar};

Hi, Remy,
That was foolish of me, one of the problems of working alone is you have
no-one to look over your code. But fixing it didn't solve the problem.
I'm listing the entire header files, in case there's something sneaky in
there.
After the two Not an allowed type errors, I get an internal compiler
error from another module.
Thank you so much just for being there!
Hugh

When forward declaring VCL classes (anything descending from TObject)
use the DELPHICLASS modifier:
class DELPHICLASS TtmCalendar;
class DELPHICLASS TtmClock;
class DELPHICLASS TtmCalendar;
class DELPHICLASS TtmClockControl;
