Hallo Benny!

 BP> will it run all c64 basic programs with peek and pokes ?

Send some example code and I'll give it a try.  All I know for sure is that
hello.bas compiles without any grief and is a pure 64-bit executable on the
x86_64-silvermont-linux-gnu host where gcc-8.2.0 bootstrapped it.  I haven't
run across any documentation that discusses compatibilty yet ... other than the
 qbasic quote Little Mikey posted in this echo.

 BP> will it do all commodore 128d basic programs with mmu and 1024k
 BP> free mem ?

I don't know.  My best guess is that it doesn't matter.  I didn't see commodore
 portabilty listed anywhere.  I did notice that freebasic can be ported to
win32, win64 and dos, as well as to linux and bsd.  I managed to get it working
 as a pure 64-bit linux without too much grief.  How about you?

 BP> google unicomal and ibm

See http://freshmeat.sourceforge.net/projects/ope... as well as the pure
linux port at https://github.com/poldy/OpenCOMAL.

Het leven is goed,
Maurice
