Last time I tried QB64, it was clunky and flaky, nothing like programming in the original QuickBASIC environment.

I use the BASIC located at portal.qb64.org to run some of my old QuickBASIC programs.

Hi Robert,

Any idea if this idea of yours is really feasible ?
What would it take to integrate this into DOS MMBasic ?

Poppy said At least I cannot find any pixel-plotting just for drawing some lines and graphs or other corresponding graphic commands ...or am I getting this completely wrong within the manual?

Absent as far as I know, and I agree, I'd like to be able to paint a screen with text and graphics. You can output [...] VT100 code to a terminal with serial out--and also feed it back into the PC with a second serial port and a VT100 terminal emulator like puTTY or Teraterm (but that's clunky and a more straightforward way of doing it would be nice (but Geoff already has a lot on his plate)).

what you are after is perhaps a bit like this?

the above (as can be seen) is mixed text and graphics displayed by GFXterm in what at first glance appears to be a console window, with the basic code running on an MX170 (MM2) attached via a serial port. however, GFXterm originated as a wrapper for MMbasic for DOS that took a turn in a different direction during development; in principal it could be adapted back to work as a wrapper for MMbasic for DOS, although this would require the two programs to work cooperatively via an API.

GFXterm implements the following graphic primatives: clear, ink, line, plot, arc, fill, moveto, drawto, scroll. graphics are drawn on a 'glass panel' that sits above the text and operates completely independently. while it looks like a console window, it is something far more convoluted and repugnant.

cheers,

it would require geoff to create a version of dos/win32 mmbasic where the onboard editor talks to the screen and keyboard solely via the STDIN and STDOUT pipes, uses vt102 escape sequences for cursor positioning, changing colours, etc, and responds to vt102 keyboard escape sequences for function and cursor keys. this could perhaps be achieved just through changing some of the conditional compile switches, as the vt102 stuff is already in the source code for use with all the pic32 micromites.

then one runs mmbasic.exe using the exact same method as 'P32P GUI.exe' runs pic32prog.exe:

this part would require me to create a variant of gfxterm that instead of talking to a serial port, is hard-wired to talk to the hooked pipes to/from mmbasic. doing this is relatively simple, all the code already exists.

cheers,
rob :-)

Hi Poppy, and

I realize you live in Germany but I always have some Colour Maximite on ebay ready to go.

I would like to suggest EngineBASIC. It is truely a Maximite, C=64, CoCo2 type experience with structured programming and modern hardware, speed, and all the graphics abilities one could ask for. If a person where happy with GW-Basic, Free-Basic, or MicrosoftBasic they will be happy with this dialect. I know your not thrilled with line numbers but this is a far superior experience to GB64 even.

https://basicengine.org/
https://github.com/uli/basicengine-firmware

There are several ways to run it including dedicated hardware, devoted emulator, and SDL versions. I work in all three. The SDL version is quite appealing as it aims to be that modern C=64 or Maximite experience on any operating system/hardware that can run an SDL application.

basic678.sdl.zip

basic678unoficial.zip

File structure:

[Engine Basic]
basic678.sdl
basic678unoficial
1mgm.sf2
[sf]
1mgm.sf2
[vfs]
[flash]
[sd]
---------------------------------------------------

Launch this SDL version in linux:
sudo ./basic678.sdl

Launch this Emulator in linux:
sudo ./basic678unoficial

To compile for your operating system:
