SUBTTL REVISION HISTORY
COMMENT \


EDIT #				REASONS
------				-------

1	CHANGED SOS INTO EDIT, CHANGING SYMBOLS, NOT COMMENTS

2	CHANGED BACKUP ROUTINE BACK TO SHORT FILE VERSION

3	Added two new commands: /? prints all the settable
	switches, and =? prints all the printable switches.

4	Re-inserted the LOCATION switch which somehow got
	lost.

5	Added ? to the Alter command.  It prints a list
	of all the valid Alter mode commands.

6	Added the subcommand to E which prints a VTECO-like
	identifying line at the top of your file if you exit
	with the option 'I'.  This feature is in under the
	FT10X switch.

7	CHANGED THE COMMAND DISPATCHER TO BE GENUINELY
	TABLE-DRIVEN.

10	MADE THE W AND Q COMMANDS TELL THE USER TO GIVE THE
	B AND EQ COMMANDS.  THE _ COMMAND TELLS THE USER TO
	GIVE THE / COMMAND.

11	Fixed a bug in the join logic, and fixed ? message.

12	Changed the TOPS-20 parser.  EDIT must be started
	by the TOPS-20 Exec, with the command in the
	RESCAN buffer.  In all other cases, the user gets:
	?You must type an input file specification.

13	The parameter CORSIZ has been added.  For TOPS-10
	programs, this parameter should be set to 3000(8);
	however for now we are setting virtual jobs at
	300000(8).  This is the number of words which will
	be in the 'core memory buffer'.  Refer to the routine
	MOCO (for getting more core).

14	Removed the ED feature which allowed the user to lose
	everything if he typed 'END'.  Also removed the EQ
	command and changed the help message.

15	put most of the code under setppn under the IFE FT10X
	conditional.

16	CONVERT TO TOPS20 MONITOR CALLS

17	FIX ^U PROBLEM IN READNM (SAVE PREVIOUS FILESPEC)
	FIX "FILE STILL MAPPED" PROBLEM IN OCOMPL

20	MAKE COPY BROWSE BUFFER 10 PAGES. CLEANUP ^O STUFF.

21	FIX WRAPAROUND ON /RO FILES THAT ARE UNSEQUENCED.
	MINOR FIX TO ^C INT WHEN NORENT IS ON. CHECK CREATF
	BEFORE TRYING TO MAKE A BAK FILE.

22	SET CORRECT FILE DATE AND TIMES UPON EXIT

23	ADD /WINDOW:N TO SPECIFY EDIT WINDOW SIZE, EJ COMMAND
	TO DO D^/^ , EI, ADD K<LF> TO ALTER MODE

24	HANDLE CHL 20 PSI AND OPENF FAILURES FOR DISK FULL OR
	QUOTA EXCEEDED. ADD CLEAR OUTPUT BUFFER ON ^C

25	REDO ERROR MESSAGE MACRO AND CODE ASSIGNMENT

26	SEE TCO FILE FROM NOW ON (ALSO FIRST COMMENT LINES)
