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 `support/` should be included first, so that system entry
|
|
|
|
|
points such as `chrout` are defined. In addition, some of these
|
|
|
|
|
programs use "standard" support modules, so those should be included
|
|
|
|
|
first too. For example:

`chrout` is a routine with outputs the value of the accumulator
|
|
|
|
|
as an ASCII character, disturbing none of the other registers,
|
2018-03-06 10:32:52 +00:00
|
|
|
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.)
