Notes on POX

Jan 78	Font loading should not cause selection of a font.

May 78	Need leftify mode (flow, but no fill).

May 78	Underline should work across line boundaries in pass-as-is
	mode.

Jun78	Need a mode where comments are not stored in macros.

18Jun78	New macro definitions should overwrite old, and there should
	be an explicit way to push macro definitions.

	Perhaps files loaded with atsign should be regarded as having
	a carriage return at the end of the last page, so that the
	page could be ended with \, to avoid trouble with lines 
	introduced by the E to SOS to E cycle.

19OCT78	First and rest of a  string  should  be  implemented  as  pox
	commands to improve speed.

22NOV78	Need a way of getting at the file name.
	Need a length of string primitive.
