This was an issue with ZEROFILL usage of INT21.7303. FreeDOS returns AX=7303 unaltered, CF=0 on success. However, MS-DOS returns AX=7300, CF=0 on failure (as it does not support this function). ZEROFILL checked for CF=1 or AX=7303 as error condition, making it fail under FreeDOS kernel. It worked with the EDR kernel because EDR returns AX=0, CF=0 on success.
