Here's a statistical breakdown of the source code for the disc version of Elite. Click on the table headers to sort by that statistic. Some notes:
- The instruction count does not include EQUB, EQUW, EQUD, EQUS or SKIP operatives used in declaring variables, but it does include them when they are buried in code (so EQUB &2C "BIT skip" instructions are counted)
- Instructions inside macros aren't counted
- Each part of a multi-part subroutine counts as an individual subroutine
