DIGITAL RESEARCH(r) CP/M Plus TM (CP/M Version 3) Operating ...

Section 5
Command Summary
This section describes the commands and programs supplied with your CP/M 3
operating system. The commands are in alphabetical order. Each command is followed
by a short explanation of its operation and examples. More complicated commands
are described later in detail. For example, ED is described in Section 6. Other
commands, such as SID and MAC, are described fully in other CP/M manuals.
CP/M 3 has replaced some commands from previous CP/M versions. @C replaces
ASM; SHOW and DIR include the previous STAT functions; and SID replaces DDT.
5.1 Let's Get Past the Formalities
This section describes the parts of a file specification in a command line. There are
four parts in a file specification; to avoid confusion, each part has a formal name:
o drive specifier-the optional disk drive A, B, C, ...P that contains the file or
group of files to which you are referring. If a drive specifier is included in
your command line, a colon must follow it.
o filename-the one- to eight-character first name of a file or group of files.
o filetype-the optional one- to three-character category name of a file or group
of files. If the filetype is present, a period must separate it from the filename.
o password-the optional one- to eight-character password which allows you
to protect your files. It follows the filetype, or the filename if no filetype is
assigned, and is preceded by a semicolon.
If you do not include a drive specifier, CP/M 3 automatically uses the default drive.
If you omit the period and the filetype, CP/M 3 automatically includes a filetype of
three blanks.
