In Borland Turbo Pascal "inline" is a real kludge which only lets you
write machine language opcodes, in an arcane format, but give it a
function name which, when invoked, copies that code directly into that
point of the program. For example, I have in my "Useful" library...

function MulDiv (x, y, z: integer): integer;
  inline ($59/$5A/$58/$F7/$EA/$F7/$F9);
  { MulDiv := x * y / z; pop cx; pop dx; pop ax; imul dx; idiv cx}

which is really useful for example for fast line slope calculations.
