In answer to a previous newitem on int16 diagnostics: I recently posted a trick in TSR.ASM via int16 to diagnose if the TSR was loaded before. The trick relies on the NORMAL int16 doing nothing when called with a funny value in AX. If the TSr is loaded then it captures the int16 call and returns something sensible when called with the agreed upon AX value. However is the particular clone MSDOS does something funny when AX is set to this value then the program can be in problem, however it works fine on all the clones I have tried! for more info please email me directly (see path in message, since i lost site of paths now that ihnp4 is going away?).
