Warning!

The BASIC interpreter is derived from copyrighted code! So the basic interpreter is only an educational example of how to port other programs from the C64 or other PET computers to the OS/A65 operating system.

Do not try to assemble it or run it!


The basic interpreter is taken from the C64. I de-assembled it into normal source code and patched it to work with OS/A65 and multitasking. Several commands are changed and others, most notably the BASIC V4 commands, are added.

new commands

Some parameter can be left off, I was just to lazy to write all the brackets...
