Some notes on the above:
- The instruction count does not include EQUB, EQUW, EQUD, EQUS or SKIP operatives; these are counted as data.
- Each part of a multi-part subroutine counts as an individual subroutine.
- The statistics are produced by a relatively simple static analysis of the source code. They are not 100% accurate, though they are pretty close.
