Hi
Would it be realistic to adjust the MMBasic prompt environment to be a sort of shell or OS ? It looks good and it has a lot of nice features, I am wondering if CFunctions can run "underneath" then maybe a CFunction could run as its own simple application ? I am probably way off track so apologies if that is so ( wouldn't be the first time :) )

It will be possible to do what you want in the very near term, just not right now

I would love to see a simple Line Edit function where Up Arrow is last command and then you can modify it into a new or corrected command.

@chronic

You're not off track at all !

In 4.7 B23 and later there is a way for a CFunction to run in the background all the time even when MMBasic is sitting at the command prompt.

goto http://www.mmbasic.org/calltable/CFuncmSec.html for documentation and example code.

Notice that if you break out of the program using Ctrl+C, the background CFunction continues to run.

CFuncmSec is the gateway to providing time-slice multi-tasking (of C code only) under MMBasic

It raises another question, can a CFunction (or similar) run
in other (within reason!) environments ? I gather it is a slab of largely
autonomous machine code ? The SD card Cfunction looks really nifty

Thank you @Chronic

The SDCard driver is closely integrated with the MMBasic Interpreter and could NOT run in any other C environment.
