Will the BASIC interpreter comptiable Microsoft QBASIC?
I wish this BASIC interpreter is QBASIC.EXE for FreeDOS
for compatibility. It's name may be "FreeQB".
Eh, we may have different goals here. I'm looking for something closer to
ANSI BASIC (actually I'm thinking of basing mine on ECMA-55 since it's free).
I just want a plain old BASIC with the ability to run shell commands. My
vision is to have a really small binary that could reasonably run on an IBM
PC and replace MS BASIC.
I don't really see a need to replace QBASIC, because FreeBASIC already
replaces QuickBASIC which I believe is a superset of QBASIC.
Really I want to to this because COMMAND.COM is just too limited for some of
the things I want to script, and I hate having to cross-communicate between
COMMAND and bwBASIC.
I tend to think GW-BASIC might be a better baseline than QBASIC. It would
at least provide a 3.31 baseline.
QBASIC is a subset of QuickBasic 4.5 - it's a kneecapped version. The
source got leaked years ago - it might be possible to give it the "Chinese
wall" treatment, if anyone were up to the task.
(Obviously I can't code a MS-style BASIC interpreter without running into
issues, as I have seen the source to a couple of their interpreters. But
as someone who knows them quite well, I'd gladly torture test one if
someone were to produce it.)
