/*      Precise types for portability and clarity of intent.

- chars are for strings or text (16 bits for Oriental or video buffers)
- ordinals are for indexes and offsets
- cardinals count how many of something
- integers can be negative
- bitsets are for bits, unknown patterns, and binary trickery
