SUMMARY
This is
a
short summary on each new DISK
BASIC "command."
You may also
use any of the EXTENDED
COLOR
BASIC commands.
(See
Getting Started
with Extended Color BASIC
or the Color
Computer
Quick Reference Card
for
a
complete listing.)
The first line gives the format
to use in typing the
command. The italicized
words
represent "parameters"
—values
which
you
can specify with
the command.
This is the meaning of some of the parameters
you may specify:
filename

a
disk must
have a
filename.
The
filename should be in this
format:
name/extension:drive number
The
name is mandatory. It must
have 1 to
8
characters.
The extension is optional.
It can have 1
to 3 characters.
The drive number is
optional. If
you do not use it when
opening
a
disk
file, the Computer
will
use drive (or
the drive specified in the DRIVE
command).

be a
number
(1,
