I am currently working a program that calls int 39h (Create sub) and int 3ch (Create file) from an interrupt. When creating a sub or file on a hard, ram, or stacker drive it works just fine. But when creating a sub or file on a floppy drive it simply halts in the middle of the interrupt call. Note that the exact same code works just fine when called from a non resident program. Is the some oddity of dos that does not allow int 39h and int 3ch to be called from a resident program when writing to floppy drive, or is there something I may be doing wrong? +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++ Tim Arheit ++ ++ ++ University of Toledo ++ (New .SIG on order) ++ ++ Electrical Engineering ++ ++ ++ tarheit@jupiter.cse.utoledo.edu ++ ++ +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
