6 ; NOTE: The OPEN system call in the CBM610 kernal is different from the
7 ; standard. It evaluates the carry flag and does a normal open if carry clear
8 ; and some strange things (output sa 15 + name on IEC) if carry set. To be
9 ; compatible with our CBM file stuff, we have to clear the carry before
10 ; calling the real OPEN.
