the rudiments of SixtyPical.

Some are meant to fail and produce an error message.

They are not meant to be specific to any architecture, but

This directory contains example SixtyPical sources which
|
|
1 |
are intentionally invalid (for demonstration purposes)
|
|

and are expected to elicit an error message from a

SixtyPical implementation.
