[net.micro.atari] 520ST LOGO -- problem with I/O

ref: ST LOGO question

	The manual "A Sourcebook for ATARI Logo" that comes with the
ST is rather sad.  I have been teaching myself Logo, an enjoyable language
very reminiscent of LISP, from this manual and LOTS of trial and error.
The manual has a number of typos which make the task of figuring out a
new (to me) language doubly difficult.

	I have reached a total block however with a command called
"READLIST (RL)" which is documented on page 45 as:

	Outputs a list that contains a line
	typed at the keyboard (input must be
	followed by a carriage return) or read
	from a data file.

	There are also two other commands which can alternatly access
a data file (READCHAR & READQUOTE) and one of then (READCHAR) is said
to be able to also access "a device"!

	The problem??  There is no indication on how to get the input
from a data file!!  As far as I can tell it always comes from the 
terminal.  I havn't been able to find any other commands which access
the disk as a file, except for the LOAD command which causes the named
file of procedures to be loaded and defined.

	The ability to read (and store!) data would make Logo a useful
language for doing some graphing I am interested in.

	Thanks in advance for any help you can give.
