DOS allows for 8 bytes in the MCB and if the program name is shorter it will add a NUL, not so if the program name is 8 bytes already. Therefore my code will print up to the next NUL after the program name. I see no drive letter in the path - why does it start with MARTIN? Are you running from a network drive? What is the output of argv[0] in this case? Georg
