This directory contains example sources which demonstrate
the rudiments of SixtyPical.
Examples that are meant to fail and produce an error message
are in the `errorful/` subdirectory.
These files are intended to be architecture-agnostic.
For the ones that do produce output, an appropriate source
under `platform/`, should be included first, like
sixtypical platform/c64.60p vector-table.60p
so that system entry points such as `chrout` are defined.
There's a `loadngo.sh` script in this directory that does this.
./loadngo.sh c64 vector-table.60p
`chrout` is a routine with outputs the value of the accumulator
as an ASCII character, disturbing none of the other registers,
simply for the purposes of producing some observable output.
(There is a KERNAL routine which does this on both the
Commodore 64 and the Commodore VIC-20. It should not be hard
to find or write such a routine for most other architectures.)
