Software Product Description
BASIC/CAPS-11, Version 1

SPD 11.5.2

DESCRIPTION:
BASIC is a high level conversational programming
language developed at Dartmouth College that uses
simple English-like statements and familiar mathematical notations to perform an operation. Due to its
conversational structure, BASIC is simple enough for
the inexperienced programmer, while having capability sufficient to control all of the system resources.

Since BASIC is a higher level language, even the novice programmer can solve complex data acquisition
and processing problems.

PRODUCT NAME:

BASIC/CAPS-11 is an incremental BASIC language
compiler that provides access to CAPS-11 's cassette
file structure.
BASIC/CAPS-11 extensions language include:
• An optional string capability. Core conscious users
can delete the string support in BASIC/CAPS-11
and reclaim the space for their programs; users
who desire have Dartmouth-compatible string support complete with string arrays and functions. At
least 16K words of memory required for string capability.
• A "CALL" statement which allows easy interface of
assembly language functions; the subroutine can be
called by name and passed several arguments.
• Sequential File support for the TA 11 cassette unit.
• Chaining and overlay support to accommodate
large programs.
• Extensive support for the PDP-11 Laboratory Peripheral Systems (LPS11), including the A/D's, RealTime Clock, Digital I/O and Display. At least 16K
words of memory are required for LPS support.
• Extensive support for the display processor in
graphics systems, making available for the user all
the hardware capabilities of that device. At least
16K words of memory required for this capability.
The file structure implemented under BASIC/CAPS11 includes provisions for one sequential file per cassette unit. The sequential files accept any type of ASCII data, and are particularly useful for stored text
and data strings.
BASIC/CAPS-11 also runs in fully interactive "desk
calculator" mode that can aid program development
and perform one-time only calculations in response to
console commands without the need for a conventional stored program.

The Laboratory Peripheral Systems for the PDP-11
(LPS11) are fully supported by the system via
modules supplied with BASIC/CAPS-11. The realtime extensions enable the user to sample and display, in real-time, a variety of data related problems
from analog to digital converters, digital input/output,
and external events. Sampling is controlled by crystal
clocks and/or Schmitt Triggers with which the user
may specify such parameters as sampling rate arid
response time.
All LPS11 commands are initiated by the BASIC
"CALL" statement. The extension contains 20 commands, divided into 5 categories depending on their
function. Each category is supplied as a separate
module allowing the user to include only the modules
necessary for a given experiment. The 5 modules are:
Module 0: Interface to BASIC/CAPS-11 (required)
Module 1: Analog to Digital conversion
Module 2: Real-Time Clock
Module 3: Digital I/O
Module 4: Display
For systems with a VT11 A Graphics Display Processor, BASIC/CAPS-11 provides a complete set of
"CALLs" to graphic routines, allowing the user to control all the hardware features of the display processor
such as vectors, alphanumerics, pOints, multi-intensities, blinks, etc. Additional commands perform tasks
such as creating and tagging subpictures (graphic subroutines), and displaying figures and arrays.
The graphic extensions provide dynamic interaction
with the system via functions for light pen interaction
and dynamic allocation/deallocation of display buffers.
MINIMUM HARDWARE REQUIRED:
Any valid CAPS-11 configuration. At least 16K words
of memory are required for string support, LPS-11
and/or display support.
