The original version of dosread/write/dir as written by me, could only
handle 360K and 1.2M diskettes. Watch out for patches that include
diskettes (hard-disks) of which the FAT entries are not 1.5 but 2 bytes.
Also you will have to check the amount of bytes used for the Root directory
and both FAT tables.

I left out the "stdio" library and inserted this limited version of
print_string, because by the time I wrote dosr/w/d, there were serious
troubles concerning the amount of disk space left. Using print_string
kept the binary about 3 or 4K smaller.
