Best text editor in CP/M

Hi.
I search a good CP/M text editor, e.g for edit pascal files. I am not looking for WordStart or so.
I found one, which should be fine, called ZDE16, is the Memotech CP/M under Memu compatible with any known terminals ?
Or is there another better text editor.?

I always used Newword in non document mode for creating assembler files.
It came with the system and is a heck of a lot more friendly than the CPM editor ED.COM.

I’d also vote for NewWord in non-document mode.
Also, there is a copy patched for 56x24 mode (N56.COM), and a copy patched for 48x80 mode (N48.COM).

I also use Newword on MTX.
However, if using MEMU, why not use your Linux or Windows editor of choice and use Andy's CP/M file system interfaces
CPMFuse or
CPMCBFS to open and save the files to your CP/M image?

You know, what would be really interesting and useful would be a non-native BASIC program editor.
Being able to write MTX BASIC programs on a machine with a larger display (width and height) with a full screen editor and then save them so that the real machine can run them would make things far more convenient.
I'd imagine that this would be quite a big job, unless you just have a program which converts the file into a text file and then another to re-tokenize the text file and recreate the BASIC binary.
P.S. I see that there is a program for extracting text from MTX BASIC files on Primrosebank (written by Paul Daniels). Maybe that can be used as a basis of generating a new BASIC file.

You can write Basic programs in a text file and then use Andy's auto-type feature to import them into MEMU. The import process is a bit slow.
To do the reverse, use the -prn-file option in MEMU and then LLIST the file.

Thinking about it, one neat solution would be an MTX command to load a program from a text file.
It should be fairly simple:
- * Read a line from file into keyboard buffer.
* Call ROM routine to process line.
* Repeat.
If the lines don't start with line numbers then they would be executed immediately, which could also be useful.
This would be much faster than auto-type as there would be no waiting for the keyboard scanning routine.
I think I have too much else on at the moment
It sounds like something Martin could do in an evening

something like a USER EXEC "filename" for CFX/CFX-II looks reasonably doable.
Looking at the rom sources
Code: Select all
.basic
LD SP,(SSTACK)
XOR A
LD (PAGE),A
OUT (&00),A
LD (PRORPL),A
RST &10 ; output routine
DB &A3 ; send 3 bytes to the screen
DB &1B
DS "V"
DB &FF
DB &6F ; select VS7 and clear
DB &A5 ; send 5 bytes to the screen
DS "Ready"
DB &68 ; select VS0 and clear
DB &1E ; send 30 to the screen
.nexkey
CALL kbd
JR Z,nexkey
CP &03
JR Z,nexkey
RST &10 ; output routine
DB &6F ; select VS7 and clear
DB &40 ; select VS0
CALL edit1
.prog
RST &28 ; Utility routine
DB &AA ; call EDEND (&1148)
JR Z,endedit
LD HL,(KBDBUF)
PUSH HL
CALL syn
RST &10 ; output routine
DB &61 ; select VS1
DB &23 ; send 3 to the screen
DB &20 ; send 0 to the screen
DB &12 ; send 18 to the screen
POP HL
PUSH HL
CALL ol1
POP DE
LD HL,(COMMAND)
CALL run8
LD BC,(AUTOIN)
LD A,B
OR C
JR Z,basic2
RST &10 ; output routine
DB &6F ; select VS7 and clear
DB &68 ; select VS0 and clear
DB &1E ; send 30 to the screen
LD HL,(AUTOST)
ADD HL,BC
LD B,H
LD C,L
LD (AUTOST),HL
CALL bcdec
CALL strout
RST &10 ; output routine
DB &81 ; send 1 bytes to the screen
DS " "

Looking at that, duplicating the code, replacing the call to KBD, with a call to the disc GET byte routine might be all that's needed.
Other than that, patching USERIO at #FD51 to intercept the keyboard read code might be possible too, but that's not reset proof and not rom-able as the setup code pages in page rom 0 immediately before making the call.
