How can I add BASIC commands to AUTOEXEC.BAT?

You can make something like my Multi-Boot. (Use an AUTOEXEC.BAS instead of the AUTOEXEC.BAT)

search bascom.com,
a:\bascom set adjuts (7,7)

Hello guys, finally I've applied a very simple solution: direct call to BASIC command of DOS. You can split your autoexec.bat in different files, and after the BASIC program continue executing whatever you want, something like this:
[AUTOEXEC.BAT]
...
BASIC config1.bas

And file config1.bas should be like:
[CONFIG1.BAS]
10 CLS
20 -- PERFORM MY BASIC COMMANDS --
30 _SYSTEM("config1.bat")

In config1.bat I apply specific config desired after the BASIC commands.

Thanks for your help!

I've heard of bascom but never tried it. I don't expect it to support everything you can do in basic, like a call for gr8net.
On top of that I wouldn't even want to begin with converting my basic booter to bascom cuz it's quite a monster with a for next loop and data lines

I reccon you've to load bascom for each command you want to perform, so after a while bascom would lose
