Atari 800 Basic Reference Manual

Disk Drives: (Dt:, D2:, D3:, D4:) Input and Output devices. If 16K of RAM is
installed, the ATARI can use from one to four disk drives. If only one disk drive
is attached, there is no need to add a number after the symbolic device code D.
Screen Editor: (E:) Input and Output device. This device uses the keyboard
and display (see TV Monitor) to simulate a screen editing terminal. Writing to
this device causes data to appear on the display starting at the current cursor
position. Reading from this device activates the screen editing process and
allows the user to enter and edit data. Whenever the l;ljiil;ill key is pressed, the
entire logical line within which the cursor resides is selected as the current
record to be transferred by CIO to the user program. (See Section 9).
TV Monitor: (S:) Input and Output device. This device allows the user to read
characters from and write characters to the display, using the cursor as the
screen addressing mechanism. Both text and graphics operations are supported.
See Section 9 for a complete description of the graphics modes.
Interface, RS-232: (R:) The RS-232 device enables the AT ARI system to inter-
face with RS-232-compatible devices such as printers, terminals, and plotters. It
contains a parallel port to which the 80-column printer (ATARI 825TM) can be at-
tached.
CLOAD (CLOA.) Format: CLOAD
CSAVE (CS.)
24 I/0 Commands and Devices
Examples: CLOAD
100 CLOAD
This command can be used in either Direct or Deferred mode to load a program
from cassette tape into RAM for execution. On entering CLOAD, one bell rings
to indicate that the PLAY button needs to be pressed followed by lam .
However, do not press PLAY until after the tape has been positioned. Specific in-
structions for CLOADing a program are contained in the ATARI 410 Program
Recorder Manual. Steps for loading oversized programs are included in the
paragraphs under CHAINING PROGRAMS at the end of this section.

Examples:
CSAVE
CSAVE
100 CSAVE
100
cs.
This command is usually used in Direct mode to save a RAM-resident program
onto cassette tape. CSA VE saves the tokenized version ofthe program. On enter-
ing CSA VE two bells ring to indicate that .the PLAY and RECORD buttons must
be pressed followed by li!IBJ. Do not , however, press these buttons until the
tape has been positioned. It is faster to save a program using this command
rather than a SAVE "C" (see SAVE) because short inter-record gaps are used .
Notes: Tapes saved using the two commands, SAVE and CSA VE, are not com-
patible
It may be necessary to enter an LPRINT (see LPRINT) before using
CSAVE. Otherwise, CSAVE may not work properly.
For specific instructions on how to connect and operate the hardware,
cue the tape, etc., see the ATARI 410 Program Recorder Manual.
