Creating Files
What Is a File?
Information stored in the system is organized in collections
or groups of data called files. You organize the information
that you store in the system in your own personal file
collection. You may choose to store a collection of short
stories on the system by putting each story in its own file.
Or a collection of memos to Mr. Smith may be stored in a
file to keep them separate from the file containing memos to
Mr. Jones. The system provides you with programs and
information that will help you choose a way to organize your
own personal file collection.
You will need a way to identify each file so that later, when
you want to use it again, you will be able to tell the system
which information to give you.
You can identify a VM/PC file by giving it its own name.
The three parts of a file identifier are filename (fn), filetype
(ft), and filemode (fm).
The filemode identifies the collection to which the file
belongs, as well as giving it certain attributes. Most data
files that you create will have a fm of AI. The "A" identifies
the file as part of your personal file collection, and the "1"
means that the file will be visible to other users with "read
access" to your personal file collection. A 1 is assumed by
the system if you do not specify fm when you issue file
