Header: Pascal 1.3: Using it on a Hard Disk 20SC

 When using Apple Pascal 1.3 (as well as versions 1.0, 1.1, and 1.2) on an
 Apple II, you cannot use the Hard Disk 20SC as a volume: since Pascal stores
 the volume size as a signed integer, it cannot work with volumes larger than
 32767 blocks. (The HD 20SC has 39165.) The Hard Disk 20SC can be formatted
 from Apple Pascal, but when you attempt to use the Pascal FILER to copy files
 to the drive, you get a "NO ROOM ON VOLUME" message. Furthermore, Apple
 Pascal only supports 77 files per directory, so even if you could use the
 Hard Disk 20SC, you would run out of directory space before you could even
 come close to running out of disk space.

 The directory limitation applies to 5 meg and 10 meg ProFile drives as well.
 You can use a ProFile hard drive with Pascal 1.3, but you cannot "share" the
 drive with ProDos: you must dedicate the entire hard drive to a maximum of 77
 Pascal files.
