  I recently posted a request for help concerning the JOVE (Ver. 4.9) editor. I
have collected  the mail that was  sent to  the  net  and  direct  to myself to
provide a brief summary to the questions i asked. Thanks to those who replyed
P.S. This is a long posting!!

|1)  I have defined, named and saved to a file a few keyboard macros
|    (no problem), but when i try to  read the  macros from the file
|    there is no command to do it. The manual states that the command
|    read-macros-from-file should be used, but it does not seem to be
|    implemented. Is this command implemented or is there an error
|    between the product and its manual ?

    Yeah, the documentation is messed up.  I should fix that.  Anyway, oh,
    and also you have a fairly old version.  It's pretty good but the latest
    is better, version 4.12.  Now, to read your macros back in you just say
	source <filename>
    the same way you can source a .joverc file.  So you can take those macros
    you wrote and put them in your .joverc if you want.

|2)  On the Vax i have a Wyse wy85  terminal set to  emulate a vt100.
|    I have  tried to  configure  the keyboard to my tastes and  have 
|    been less than successful. I have tried to bind-to-key commands
|    with the numeric keypad and also the four cursor keys. In respect
|    to the cursor keys i have been able to use the Prefix-3 command
|    in my .joverc file at startup. The problem as far as i can tell 
|    is that the keypad and cursor keys seem to generate a 3 byte code
|    instead of the normal 2 byte code. Has any one an idea how i can 
|    use the keypad, cursor keys and function keys to execute commands ?

    You can say "bind-to-key prefix-3 ^[[" and then you can say 
	bind-to-key next-line [A
    or whatever the right sequence is.  In the latest version of JOVE you
    can create keymaps with names and bind keymaps to keys, and so basically
    handle arbitrary key sequences.  Unfortunately, they are not sparse
    keymaps, so, well they can be expensive.  That's on my list to fix.

    >Jove will *only* accept two characters for any command, (i.e. ESC letter).
    >Since some terminals output "ESC [ A" for an arrow key,jove complains that

    Not true. I use Jove Version 4.9 (as I type this), and my .joverc contains:

    bind-to-key prefix-3 ^[[
    bind-to-key execute-named-command ^[[A
    bind-to-key apropos ^[[B
    bind-to-key pop-mark ^[[C
    bind-to-key next-window ^[[D
    bind-to-key scroll-left ^[[E
    bind-to-key scroll-right ^[[F
    etc
    and that works fine (on a "ansi" Tektronix 4105).

    We use JOVE extensively here, but Version 4.6 I fixed various bugs in this,
    and I have implemented keybindings for a variety of terminals. However, I 
    had to hack the code to implemenent Prefix-4, Prefix-5 (even Prefix-6 if I
    remember correctly) to handle the problem that you mention. Here is an 
    example of what the VT100 keybinding looks like.

    Up  Down  Left  Right		 PF1	 PF2 	 PF3	 PF4
    (as expected)
	        			Beg of	Left	Right	End of
		        		LINE	WORD	WORD	LINE

           		 with ESC --->	Split	Switch	Enlarge	Kill
		         		WINDOW	WINDOW	WINDOW	Other WINDOW	
    Numeric pad:			  7	  8	  9	  -
	        			YANK	COPY	KILL	Page
						Region	Region	DOWN

					  4	  5	  6	  ,
					SPELL	FILL	(spare)	Page
						Para		UP

					  1	  2	  3	ENTER
					List	Select	Find	  |
					BUFFERs	BUFFER	FILE	  |
								SHELL
					  --- 0 ---	  .	  |
					    COMMAND	OvrWT	  |
					    		Toggle


	Numeric pad, 	with ESC --->	7 (IC)	----	9 (DC)	-----
					Set	 	Exch
					MARK		. & m
	
					----	----	----	-----	
	
					1 (IL)	----	3 (DL)	  |
					Insert		Delete	  |
					LINE		LINE	  |
								  |
					  ---------	-----	  |

    However, one of the jobs I have to do soon is to make a vt220 binding,
    which might be better for a Wyse. I doubt if our bindings would  work
    immediately on Version 4.9, but maybe I could send them if you are
    interested.

|3)  I wish to have a form of programming on-line help available. I
|    have created a text file of the most popular 'C' commands i.e.
|        int  ferror(stream);    FILE *stream
|    and wish to be able to view a specified commands syntax easily.
|    The simple way to do this is to use shell-command-with-typeout
|    and then 'grep <command name> helpfile'. Considering that on-line
|    help should be quick and easy to access the outlined solution 
|    has fallen short in both respects. I would like to be able to 
|    activate a help macro (or whatever solution) by just selecting
|    the word that the cursor (point) is on i.e. cursor is in the 
|    middle of the word 'read(' and it would list all the correct
|    syntax for the 'C' command 'read'. Any suggestions ?

    From: unido!mcvax!sun!jpayne (Jonathan Payne)

    You could write a keyboard macro to make a copy of the word the cursor is
    on, and fire up the shell-command-with-typeout with that word (by yanking
    it into the buffer).

|4)  Has anyone written any interactive macros that use the command
|    make-macro-interactive. If so could you please post or mail an
|    example(s).

    From: unido!mcvax!sun!jpayne (Jonathan Payne)

    define-macro search-forward-and-split-window ^[xsearch-forward^M^[i^X2

    This prompts for a string, a different string everytime (because of the
    ^[i which makes the macro interactive) and then searches for it, and then
    splits the window.  A useless macro, but it makes its point.

|5)  I have been tinkering with word abbreviations and would like to
|    know if there is a limit to the number of abbreviations JOVE
|    can handle. I entered over 150 and when i saved the abbreviations
|    and later used some of them i found that only about 65-70 had 
|    been saved. If there is a limit can it be changed ?

    That sounds like a bug to me!  If some of the abbrevs were the same as  
    others, except maybe differing in case, that might explain the problem.
