You can execute a TRSDOS system command whenever you see the
TRSDOS Ready prompt. The command you type can consist of up to
79 upper or lower case characters. You must enter the command by
pressing

to
see the TRSDOS system commands,

Disk Files
You can keep a record of anything you type into your Model 4 by
storing it
on
disk
in
a "disk file." A disk file can contain a program, a
collection of data, a project report you intend to make, or almost
anything you want it to contain. But whatever it
is,
if you want to keep
it permanently, you'll have to store it
in
a disk file.
When the computer stores the file, it records the name of the file and
its disk location
in
a special place on the disk called the disk's
directory. Whenever you want to access the file, the computer can
immediately find its location by using this directory.
Filespec
Whenever you create a disk file, you need to give it a name. This
name is just one part of a file specification - filespec, for short. The
filespec is the standard TRSDOS format you'll use every time you
reference your file:
