Revision:	1.7
Committed:	2002-01-18T16:03:33Z (22 years, 3 months ago) by cebix
Content type:	text/plain
Branch:	MAIN
Changes since 1.6:	+1 -1 lines
Log Message:	- copyright year bumped to 2002 - in MacOS mode, mon pulls in the lowmem globals as predefined variables - mon_lowmem.h split into .h/.cpp because it's now used in two places - variable handling code rewritten to use map<> instead of manually maintained linked list
