Commodore OS Vision Forum

Hi all...noob here but learning fast. I should say...relearning LOL.
For commodore Basic, which program do I launch? The commodore emulator doesn't recognize some commands such as for loops and commodore OS basic program doesn't do some graphics commands. Nedither of these look like the emulators I see online for programming examples.

Please help

Hi NibbleNut,

To use Commodore OS BASIC at the moment, you need to run the specific editor for it.
From the top menu:
Applications --> Programming --> Commodore OS BASIC Studio
This is broken on COS3 Beta 6 and will be fixed as part of the update coming soon.
If you downloaded COS3 you have beta 8.
If you are programming in Commodore OS BASIC I would urge you to save files outside of it's application base path, like say to your Documents folder, as I may have to delete or clobber application files on updates.

The retro interface version, which is the first option in the programming menu is still in the very, very early development stage.

Please let us know how you go in your BASIC development even if it is small.
My focus will soon be shifting to enhancing the experience and developing the multi platform part.
That doesn't involve enhancing BASIC on the C64 as such, so you won't be able to use the new BASIC on classic machines.
Rather you would develop in BASIC on Commodore OS and compile a binary to run on the classic machines.
Please note, that only a subset of the commands in Commodore OS BASIC will be available for this process and the commands and language will evolve.

I do have beta 8 and that's what I've been using (basic studio). Now I know it's broken, I can wait that's fine, however, since I got C64 forever to run, I'm able to run the original C64 basic. I just can't figure out how to save my programs.

Everywhere says you have to setup a D64 drive.

btw.....love what you do here. The nostalgia you bring is amazing.

You might want to try out CBM prg Studio from the programming menu.
It lets you program in BASIC via an editor and then run it in an emulator.
You must run the Cloanto 8-bit ROM setup from the Settings Manager for it to work.

BTW Commodore OS BASIC Studio should not be broken in Beta 8. Try running the Beast demo project under graphics examples.

ok..ya, that works. Ok, awesome. There were just some commands that didn't work like boxfill, etc but beast runs well so I'll go with that.

\Thanks again.

Update: Working well. Learning lots. I can see that this is a new basic though and not the original C64 with Sprites. Recall, I can run the original under C64 forever but cannot save my programs.

Anyway, here is what I've been playing around with. Still early stages but makes me smile. Replace sounds and images as you see fit OR comment them out.
