This program operates on PLATO packs and master files. Packs are accessed as DtCyber disk images. Master files (CDC style virtual packs) can be accessed directly (if you have a master file image copy available) or as NOS files contained in a NOS disk image.

<Documentation_reference>

When accessing PLATO file structures, the host pack object needs to be instantiated and then the PlatoFile class may be used to access the underlying structure.

Mapping of Account Common (s0files:accountcom)

The account common is the central storage of filename information for all accounts.

The information in the account common is a set of arrays built at system installation/initializion. The lists don’t shrink or grow so they are managed “in place”.

add_file(filename: str | int) → int

Adding a file means inserting into the list.

commit() → None

del_file(filename: str | int) → int

dump() → None
