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