33 Examples that are meant to fail and produce an error message
44 are in the `errorful/` subdirectory.
55
6 They are not meant to be specific to any architecture, but
7 many do assume the existence of a routine at 65490 which
8 outputs the value of the accumulator as an ASCII character,
6 These files are intended to be architecture-agnostic.
7 For the ones that do produce output, an appropriate source
8 under `platform/`, should be included first, like
9
10 sixtypical platform/c64.60p vector-table.60p
11
12 so that system entry points such as `chrout` are defined.
13
14 `chrout` is a routine with outputs the value of the accumulator
15 as an ASCII character, disturbing none of the other registers,
916 simply for the purposes of producing some observable output.
10 (This is an address of a KERNAL routine which does this
11 on both the Commodore 64 and the Commodore VIC-20, so these
12 sources should be usable on these architectures.)
17
18 (There is a KERNAL routine which does this on both the
19 Commodore 64 and the Commodore VIC-20. It should not be hard
20 to find or write such a routine for most other architectures.)
