(Usually I'm only this dense on Mondays & national holidays...) The line F compression I refer to is a method we used in ST ROM which basically replaces common operations with line F instructions. The line F handler is able, by decoding the $Fxxx instruction, to determine what operation to perform. The handler then dispatches the exception to the appropriate OS routine. -- ||| Ken Badertscher (ames!atari!kbad) ||| Atari R&D System Software Engine / | \ #include <disclaimer>
