Password; Sample File Specif Ication; User Number - Commodore 128D User Manual

Password
In the Commodore 128's CP/M 3.0 you can
include a password as part of the file specifica
tion. The password can be from one to eight
characters. If you include a password, separate
it from the filetype (or filename, if no filetype is
included) with a semicolon, as follows:
CUSTOMER.NAM;ACCOUNT
A password is optional. However, if a file has
been protected with a password, you MUST
enter the password as part of the file specifica-
tion to access the file.
Sample File
Specification
A file specification containing all four possible
elements consists of a drive specification, a
primary filename, a filetype and a password, all
separated by the appropriate characters or
symbols as in the following example:
A:DOCUMENT.LAW;SUSAN
User Number
CP/M 3.0 further identifies alLfiles by assigning each one a user
number which ranges from Oio 15. CP/M 3.0 assigns the user num
ber to a file when the file is created. User numbers allow you to sepa
rate your files into 16 file groups.
The user number always precedes the drive identifier except for
user 0, which is the default user number and is not displayed in
the prompt. Here are some examples of user numbers and their
meanings.

User number 4, drive A

number like this:
The screen displays:
