Entering
a Command
Whenever
the trsdos prompt,
TRSDOS READY
is displayed,
you can
type in a command,
which
can
be no
more than
63
characters
in length. You
must press
(ENTER)
to end
the line,
trsdos will
then
"accept" the command.
For
example, type: CLS
CENTER)
trsdos will
clear
the Display
and
the trsdos
ready
prompt will reappear.
In general, your commands
will
require
more than
one word.
For
example,
to
kill (delete)
a
file
named myname,
you have to
specify
the command
and the
filename.
KILL MYNAME
(ENTER)
tells
trsdos
to
find
the file named
myname,
eliminate
it from
the diskette,
and
release
the space previously
occupied
by that
file.
Whenever
you type in a line,
trsdos
follows
this procedure:
1
.
First it checks
to see if what
you've
typed
is the name
of
a trsdos
command.
If it is, trsdos
executes it
immediately.
2.
If
what
you typed is
not a trsdos
command,
then trsdos
will
check to
see if
it's the name of a program
file
on one
of the drives.
3.
When
searching
for a file, trsdos
looks
first
through
Drive
0,
then Drive
1,
etc., unless
you include an
particular
drive
specification
with
the file
name
—
or specify
the master
command
(see
Library
Commands).
If trsdos
finds a specified
user file,
it will
load
and execute
the file if
it is a
program
file. Otherwise,
you'll
get an
error message.
Command
Syntax
Command syntax
is a command's
general
form (like
the grammar
or structure
of
an English
sentence). The
syntax
tells how
to use
keywords
(such as dir,
list,
create,
etc.) together with
the necessary
parameters
and punctuation.
If
you need help remembering
the
syntax
form of
a specific command
while
you're operating trsdos,
type in:
HELP
command (ENTER)
