PropBasic compiles OK, Spin doesn't:

Is this a bug?
Kind regards, Friedrich

Fried,
Yes that is a bug.
Here is a corrected version of the compiler (version 1.25).

Thanks very much Bean,
could you please also have a look at PropBasic & Libraries.
I don't know if I can build programs this way, it is a bit "C"-style.

Fried,
I never intended LOAD to be nested. It's not going to work. It will probably stop after 1 level and never return to continue compiling the main program.

hey bean, i think this update caused some problems for me. code is attached, you might recognize it from the viewport thread.
thank you sir!

edit: looks like i get the same error with v1.24 as well...last version i have that worked is 1.19, but i havent tried anything in between.

error:

---------- Capture Output ----------

I'll check it out.

Bean

I see the problem.

A task cannot start another task. The addresses of the tasks are held in the main program's COG RAM, so it is not readable from other tasks.
I could store it in HUB ram, but that will take some work to shuffle everything around.

I'll put it on the list of things to fix.

thanks again bean! take you time, honestly that was kind of a sloppy work around, i should rethink it. I have this weather box on my desk running all the time, so its an easy thing to test revisions on.
