Input
from

BUILD-FIie
illlllllllll^^
This
command
reads and
executes
the lines stored
in a special-format
file
created
with
the
build command. The
System
executes
the
commands
just as
if
they
had been
typed
in
from
the
Keyboard.
Command
lines
in a
build
file
may
include
library
commands
or
file
specifications for user programs.
When
do
reaches
the
end
of the automatic
command
input
file,
it
returns control
to
TRSDOS.
The debug
and
clear command
cannot be
included
in a
build
file.
In
addition
to
executing trsdos
library
commands,
you
can
load
and
execute
user
programs from
a
DO-file.
You
will
probably want
to
make
your program
name
be the
last line in the
Do-file.

prompts.

start
trsdos,
it
will begin automatic
command
