In Appendix D: Disk Errors, page 174 reads:
67 Too many files An attempt is made to create a
new file (using SAVE or OPEN)
when all 255 directory entries
are full.
It should read:
67 Too many files An attempt is made to create a
new file (using SAVE or OPEN)
when all directory entries are
full. The CP/M limitation for
a diskette is 48 files; the
hard disk limitation is 512.
However, if you use files larger than 16K you will have two directory entries
for the file. If the file happens to be over 32K there will be three entries.
This 16K is a file boundary for CP/M, irregardless of block size.
