;
;	Future plans :
;
;		- Possibility to save commandbuffers in a file before exiting
;		  and read them back when starting.
;
;	Known problems :
;
;		- MCE has some problems with DCL and installed tasks. DCL does
;		  not wait for installed tasks to complete. Compare the two
;		  examples below:
;
;			MCR			DCL
;
;			+>INS $FOO/TASK=FOO	+$ INS $FOO/TASK=FOO
;			+>RUN FOO		+$ RUN FOO
;			>			+$
;
;		  To solve this add the following line to MCEINI.DCL :
;
;			 R*UN := RUN 'P1'/STATUS:TASK
;
;		- Problems with older versions of RSX :
;		  You may get an undefined reference from the
;		  taskbuilder when running on an older RSX system :
;
;		  T.V2XX - Terminal definitionbit for VT2XX. The RSX-system
;			   you are running on does not support the VT2xx
;			   terminal. Include "GBLDEF=T.V2XX:36" in MCETKB.CMD
;			   and build MCE again with "@MCEBLD LINK".
;			   To use the VT2XX functions use MCR command
;			   "SET /TERM=TI:36"
;
;	Remarks on 8-Bit terminals and lines :
;       ====================================
;
;	A VT2xx/VT3xx terminal in 7-bit mode always sends "normal" escape-
;	sequences :
;			  PF1  = ESC [ P       ( 33, 133, 120 )
;			  F20  = ESC ? 3 4 ~   ( 33,  77,  63, 64, 176 )
;
;	The EBC, RPA, PASTHRU settings of the TI: donot have influence
;	on the right processing of those keyes.
;
;	A VT2xx/vt3xx terminal in 8-bit mode sends other sequences :
;
;		          PF1  = SS3 P         ( 217, 120 )
;		          F20  = CSI 3 4 ~     ( 233,  63, 64, 176 )
;
;	The EBC, RPA, PASTHRU settings of the TI: do have influence on the
;	right processing of those keyes.
;	Although they do different things one of the options MUST be on
;	to let MCE see the keypad keys.
;
;	The IO.RST used by MCE sees the folowing terminating characters in
;	IOSTB+1 :
;
;		EBC	 RPA	PASTHRU    SS3      CSI
;		 0        0        0         0       33
;		 0        0        1        17       33
;		 0        1        0        17       33
;		 0        1        1        17       33
;		 1        0        0       217      233
;		 1        0        1       217      233
;		 1        1        0       217      233

;	=========================================
;	Notes on VERSION V4.22 from  October 1988
;	==========================================
;
; Version V4.22 has the following new features : (since V4.21c)
;
;	- Rearanged the whole program to make it more readable ( I Hope )
;
;    	- NEW Internal command : "MCE ECHO on/off"
;	  When on MCE echoes commandlines to TI:. This is usefull in 
;	  INIT-files to display messages ect. ( see example below )
;
;    	- NEW Internal command : "MCE PROMpt on/off"
;	  Switches extended prompt on/off.
;	  The default setting can be specified at MCE build time.
;
;    	- NEW Internal command : "MCE OVERstrike on/off"
;	  When on MCE goes back to OVERSTRIKE mode when prompting for a new
;	  command. The default setting can be specified at MCE build time.
;	  When "ON" : Auto-insert mode is switched off
;    	  "MCE INSErt ON" Switches Auto-Overstrike mode off.
;
;	- Changed the definition of compound commandlines. Now The "&" MUST
;	  be preceeded by at least one space. This is done to let commands
;	  as "PIP /TD&/LI" still work.
;
;	- Changed the lay-out of the translation buffer print-out so that
;	  it is more "readable"
;
;	- Command definitions donot have to end with a space character
;	  to append more text.
;	  In older versions with "? := HELP" defined "? PIP" resulted in
;	  "HELPPIP". This was solved by defining "? := HELP ".
;	  Now this is not needed anymore.
;
;	- All commands may be preceded by and contain more than one TAB
;	  and/or spaces. This means that e.g. command definitions can be
;	  made more "free-style" instead of the fixed format of " := "
;	  ( exactly one space before and after the ":=" )
;	  This is usefull in init-files. The lay-out of these files can be
;	  made more "readable" now. Comments are ( and were already ) possible
;	  behind "!" for this is the comment character for CLIs.
;
;
;	  Example of an init-file:
;
;		!
;		!	LB:[1,2]MCEINI.MCR
;		!
;			MCE   STATUS   ON
;			MCE   SVINTERN OFF
;		!
;			? 		:= HELP
;			AS*SEMBLE 	:= MAC @'P1'ASM
;			CO*PY 		:= PIP 'P2'/NV='P1'
;			D*IR 		:= DIR
;			FO 		:= FOR @'P1'FTN
;			F20 		:= CLR
;			LI*NK 		:= TKB @'P1'TKB
;			MO*VE 		:= PIP 'P2'/NV='P1' & PIP 'P1';0/DE/NM
;			RE*NAME 	:= PIP 'P2'='P1'/RE
;			R*UN 		:= RUN
;			BLD 		:= MAC @'P1'ASM & TKB @'P1'TKB
;		!
;		! MCR Commands ...
;		!
;			CLR		! Clear screen
;			MCE ECHO ON	! Echo on
;		!
;		! *WARNING* -- This is a test version of MCE. Please report
;		!	       any problems to the system manager.
;		!
;			MCE ECHO OFF	! Echo off
;			TIM		! Show time
;		!
;		! End of LB:[1,2]MCEINI.MCR
;		!
;
;       Bugs fixed :
;		- When UIC is changed MCE READ or MCE REPL still were reading
;		  the MCEINI-file from the old UIC. 
;		  This problem is fixed and works fine for M. For M+ with
;		  named directories unknown.  PLEASE REPORT !!!
;
;		- The releasenotes on V4.21c didn't mention that <GOLD><RESET>
;		  does the same as in EDT.
;
;		- A second <SELECT> or a <RESET> did not clear the inversed
;		  part of the commandline directly.
;
;		- " BYE" or " LOG[out]" (note the space) where not processed
;		  well by MCE.  This is solved by removing all blanks from
;		  the commands.  ( see above )
;
; +-------------------------------------------------------------------------+
;
;	==========================================
;	Notes on VERSION V4.21c from  august  1988
;	==========================================
;
; Version V4.21c has the following new features : (since V4.21b)
;
;	- MCEBLD on a M+ system asks for I & D Space task
;
;	- <SELECT>, <REMOVE>, <INSERT-HERE> do the same as in EDT
;
;	- Same for <SELECT>, <CUT> and <PASTE> from keypad
;
;       - When the FIFO or the translationbuffer is listed the screen is
;	  cleared before displaying ( Only ANSI terminals )
;
;	- When starting MCE via a remote terminal (RT:) problems may occur
;	  if the local system is VMS with its commandline editor enabled.
; 	  The way MCE acts when it detects if it was started via a remote
;	  terminal can be specified at build time. One of the following
;	  options can be selected :
;
;	  o  Give the folowing message:
;
;      		MCE -- ** WARNING ** Started on a remote terminal (RT:)
;             	       If your local system is VMS with its commandline editor
;		       enabled please type "MCE EXIT"
;
;	  o  Give the folowing message and exit :
;
;		MCE -- Started on a remote terminalline (RT:) Exiting .....
;
;	  o  Do nothing
;
;	- The defaults for STATUS ON/OFF, SVINT ON/OFF,  SVOLD ON/OFF and
;	  KEYPAD ON/OFF  can be changed at MCE build time.
;
;    	- NEW Internal command : "MCE INSErt on/off"
;	  When on MCE goes back to INSERT mode when prompting for a new
;	  command. The default setting can be specified at MCE build time.
;
;       Bugs fixed :
;		- Fixed the wrong parameter parsing when more than 1 space
;		  was between the parameters.
;               - Fixed the problem with MCE on remote (DecNet) terminals.
;		- Task without alternate CLI support did not handle VT52
;		  hold-screen mode correctly.
;		- Task without alternate CLI support did show if KEYPAD
;		  was ON in the extended prompt
;		- With compound commandlines enabled a "&" as the last
;		  character on a line let MCE behave strange.
;
; +-------------------------------------------------------------------------+
;
;	==========================================
;	Notes on VERSION V4.21b from  june    1988
;	==========================================
;
; Version V4.21b has the following new features : (since V4.21a)
;
;       - When a command in a compound commandline ( & used ) gives
;	  a non-successfull exit status, MCE terminates the compound
;         commandline there showing the exitstatus and the command that
;	  caused it.
;	- MCE now indentifies its self with "MCE -- MCR-Commandline editor .."
;	  when no alternate CLI support was included.
;	- <CTRL/X> now executes a command leaving the fifo pointer in
;	  position. <DOWN> than retrieves the next command in a sequence.
;
;       Bugs fixed :
;		- When the <HELP> key was never used, a second <NXT-SCREEN>
;		  keystroke gave a "HEL - Unknown HELP qualifier" message.
;		- Only test for DCL's LOG[out] when alternate CLI support
;		  is included.
;		- Clear status line with MCE STAT OFF command.
;		- When saving of internal commands was disabled by an INIT
;		  file and the first "normal" command was an internal one
;		  it was saved leaving the fifopointer corrupt.
;		- Starting MCE with a filespecification on the commandline
;		  did not work.
;
; +-------------------------------------------------------------------------+
;
;	==========================================
;	Notes on VERSION V4.21a from  june    1988
;	==========================================
;
; Version V4.21a has the following new features : (since V4.2d)
;
;       - Changed Helpfile lay-out
;       - When Helpfunctionkey is used screen is cleared before display
;         of Help text ( Only ANSI terminals )
;       - <NEXT-SCREEN> and <PREV-SCREEN> on a VT2xx/VT3xx terminal display
;         next or previous Help page. ( Only works if helpfile and task
;         are generated together )
;	- When in DCL : Support LOG[out] ( same as BYE in MCR )
;       - Possible to disable the "+" , "-" and ":" characters
;         in MCE's prompt. That is : Use only CLI's prompt.
;         ( Idea from Eckart Meyer )
;       - MCE takes version number from .IDENT directive or TKB IDENT
;         option.
;       - Show "KEYP=no" in statusline when EDT-Keypad support is not
;         supported.
;
;       Bugs fixed :
;		- When in DCL the LOG[out] command caused MCE to exit with
;                 outstanding I/O and leaving the statusline on the screen.
;		- When in DCL and DCL was built without MCR as its catchall
;                 task the BYE command and the terminal Time-out only exited
;                 MCE leaving the user logged in.
;		- Moved some data between PSECTS ( RW & RO data )
;               - Fixed undefined references with no EDT-keypad support
;               - Fixed undefined references with no INIT-File support
;               - Fixed a problem in MCEBLD.CMD so that MCE now REALY is
;                 built as a multi-user task when specified in the answer.
;

;
;	=========================================
;	Notes on VERSION 4.2d from  may      1988
;	=========================================
;
; Version 4.2d has the following new features : (since V4.2c)
;
;	- Support for compound commandlines; Use of the ampersand (&)
;	  sign in command definition. E.g.
;
;		STAT := TIM & DIR & ACT /ALL
;
;	  defines STAT as a sequence of CLI-commands that are executed
;	  one after another. MCE waits for completion of one command
;	  before activating the next. Only completion of the last
;	  command depends on the WAITFL-status.
;
;	  Support for compound commandlines was written by:
;						John Bovenlander
;						Erasmus University Rotterdam
;
;	- Support for two different kind of helpfiles (HELP MCE or HELP /MCE)
;         ( Idea from W. Uelpenich )
;

;	====================================
;	Notes on VERSION 4.1a from 14-oct-87
;	====================================
;
; Version 4.1a has the folowing new features :				;JHA09
;
;  	- <CTRL/N> : Save commandline without executing
;	- An other <PF2> keystroke searches further back in the Fifo
;	  for a command that matches the definition
;	- <PF2> Recall search strings are saved until a new one has been
;	  typed in.
;    	- NEW Internal commands :
;		"MCE RING"         FIFO will be handled as a RING-buffer
;		"MCE LIST"	   FIFO is a LIST ; UP- and DOWN-Arrow keys
;				   stop at start and end.
;				   ( like in older versions )
;		"MCE FREE"	   Gives MCE Pool information
;		"MCE CHAIn"	   Synonym for READ for use in initfiles
; 	        "MCE FISZ n"	   Changes the default FIFO-size to n
; 	        "MCE CMSZ n"	   Changes the default commandlength
;				   to be saved to n
;	- Improved error messages
;	- MCE READ or MCE REPLA  with only a space for filename take only
;	  SY:MCEINI.cli as init file; without anything both LB:[1,2] and
;	  SY: will be read.
;	- Named directories always included (No problem with RSX11M)
;	- Comment and code improvements
