Some notes on the above:
- The instruction count does not include EQUB, EQUW, EQUD, EQUS or SKIP operatives; these are counted as data even when they are buried in code (so EQUB &2C "BIT skip" instructions are counted as data, for example).
- INCBIN files are not included in the counts, so the data count doesn't include bytes from binary source files.
- 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.
- The totals cover all code in the project, including loaders, docked and flight code, Tube code and ship data files.
