COMMENT	#

Edit	Description

*****   Start of version 2   *****

1	11-Oct-83 by Bill Davenport

	Complete reworking of original program to address issues
	raised by QAR 125588.  Based on earlier program of same
	name by Stu Grossman.

2	25-Oct-83 by Bill Davenport

	Fix the copying of user-id, account, and password to respect
	the size of those fields in an access information block (AIB).
	Also fix allocation of string storage to allocate enough room
	for trailing null bytes.  Increase size of atom buffer to avoid
	ABS stopcodes from GLXSCN.

3	28-Nov-83 by Bill Davenport

	Fix the NFT command files to include /ASCII so that transfers
	to systems other than TOPS-10 and TOPS-20 work properly.  Also
	change the title output at startup to print the DECnet version
	number instead of the NIPGEN version.

4	30-Nov-83 by Bill Davenport

	Up the number of KLs supported under TOPS-10 to six!

5	1-Dec-83 by Bill Davenport

	Fix the /ASCII switch again.  It belongs on the right side
	of the NFT commands, and not on the remote node's file-spec.
	Also change questions asking about the "configuration" to
	ask about what should be "tested".


; Revision History continued on next page
; Revision History continued from previous page


****    Start of version 4 for DECnet version 4.0    ****

6	9-Feb-84 by Bill Davenport

	Many changes to make runable on TOPS-20.  Largest is
	conversion to use OPRPAR for parsing.

7	15-May-84 by Bill Davenport

	Add feature test FTUNSUPPORTED to exclude support of un-
	supported hardware.

10	30-Aug-84 by Bill Davenport

	Use new GLXLIB routine K%ECHO to disable terminal echoing of
	passwords.

11	7-Sep-84 by Bill Davenport

	Rework all questions dealing with adjacent nodes.

12	13-Nov-84 by Bill Davenport

	Add questions dealing with dependent nodes.

13	27-Nov-84 by Bill Davenport

	Changed maximum acceptable node number to 1023 for DECnet
	phase IV.  Change the ethernet circuit identifier to NI-n-n
	for TOPS-20.

14	17-Dec-84 by Bill Davenport

	Changed node address parsing to allow specification of area
	numbers.  Also changed program structure to make this work.
	Add code to ask for NML access information for MCBs.


; Revision History continued on next page
; Revision History continued from previous page


15	15-Jan-85 by Bill Davenport

	Add SET CIRCUIT x STATE ON commands to the NCP.CMD file.
	Change dependent node dialog into downline load dialog.
	Add complete support for downline servicing of LAT(PLUTO),
	LAT(LAT-11), and MCB nodes.

16	24-Jan-85 by Bill Davenport

	Set flags to ask about file transfer tests defined in the
	remote node definition section.

17	14-Mar-85 by Bill Davenport

	Add SET CIRCUIT SERVICE ENABLED commands for all service
	circuits.  Close a hole which could trap a user trying to
	insert more circuits than are in parse table (by duplicating
	circuit of last entry).

20	20-Mar-85 by Bill Davenport

	Remove CI circuits from TOPS-10 supported list.

21	1-Apr-85 by Bill Davenport

	Change TOPS-10 ethernet circuit name to ETH-n.  Output SET
	CIRCUIT commands at end of NCP.CMD file.  Make sure each
	circuit gets output only once.

22	3-Apr-85 by Bill Davenport

	Change adjacent node definition section to recognize MCBs and
	to generate the correct service information.  Incorporate the
	service information block into the node information block.  Ask
	about additional downline loaded nodes after asking about any
	adjacent nodes.

23	6-May-85 by Bill Davenport

	Remove all LAT related dialog.  This dialog will form the basis
	for the new LATGEN program.

24	4-Sep-85 by Leo
	Do Copyrights.

25	11-Nov-85 by Carl Appellof

	Fix "SET NODE nnnn NAME xxxx" to use area.address in GENNCP.
