Maybe in the later days but Turbo Pascal originally was written in, AFAIK,
100 percent assembly code, with not a single source comment...

Anders was very secretive about his code as he didn't want people to steal
it.... and protected it closely....

In the later (or latter) days, Borland decided that assembly code was not
so easy to maintain... I thought they made this decision in delphi days,
but maybe they made in at some point in Turbo Pascal days and converted
some of Anders assembly to turbo pascal.
