Software Product Description
PRODUCT NAME: PDP-11 BASIC-PLUS-2N AX, Version 1.0
DESCRIPTION:
BASIC is a conversational programming language developed at Dartmouth College that uses simple English-like statements and familiar math notations to
perform operations.
The BASIC-PLUS-2 language is a superset of Dartmouth BASIC. In addition to the elementary BASIC
statements, BASIC-PLUS-2 also features:
• Terminal-format files
• Virtual arrays
• RMS Record I/O
• Extensive string support
• Full matrix package
• Long variable names
• IF..THEN .. ELSE
• ON ERROR condition handlers
• Statement modifiers: IF, WHILE, UNLESS, FOR
• User-defined functions
• Multi-statement lines
• Multi-line statements
• Program segmentation: SUB, CALL, CHAIN, COMMON
• External subprograms
BASIC-PLUS-2 uses the full ASCII character set for
its alphabet.
The BASIC-PLUS-2 language processor is composed
of a compiler and an Object-Time System/Library.
The BASIC-PLUS-2 compiler produces an object
module from a source program. The compiler checks
each program line for syntax errors and returns an
appropriate message if an error is found. The user
can then correct the program (if necessary) and compile it. Program compilations result in an object module that can be linked and executed at the operating
system command level. BASIC-PLUS-2 provides a
traceback mechanism that traces the path of program
execution when an error occurs in a function or subroutine.
The BASIC-PLUS-2 Object-Time System/Library contains the following runtime routines:
• Math routines which include library functions and
arithmetic routines
• Routines to handle dynamic allocation of string
storage and 110 buffers
• Routines to handle input/output operations

SPD 25.10.1

• Error handling routines to process errors in arithmetic, I/O and system operations
BASIC-PLUS-2 allows the user to write subprograms
and insert them into OTS or user libraries. These
subprograms can be written in BASIC-PLUS-2 or in
MACRO assembly language, and are accessed by the
CALL statement. Furthermore, BASIC-PLUS-2 programs can access any system library routines that
utilize the FORTRAN calling sequence.
BASIC-PLUS-2 Record I/O operations are controlled
with the Record Management input/output system. It
provides sequential, relative, and indexed file organizations. Features also include primary and alternate keys, fixed and variable length records, and record mapping.

ADDENDUM
SOFTWARE SUPPORT CATEGORIES
Each software product (hereinafter 'SOFTWARE') with a designated Support Category A or B In the applicable Software Product
Description (SPD) existing at the time of order will be the current release at the time of delivery and will conform to the SPD.
DIGITAL's sole obligation shall be to correct defects (nonconformance of the SOFTWARE to the SPD) as described below. Any
SOFTWARE with a designated Support Category C will be furnished on an 'as is' basis.
For SOFTWARE with a deSignated Support Category A or B, DIGITAL will provide the services set forth below without additional
charge.
CATEGORY A
1. Upon notification by customer to the nearest DIGITAL office that the computer system, including all required prerequisite
hardware and software, is ready for the installation of the SOFTWARE, DIGITAL will install such SOFTWARE in any location
within the contiguous forty-eight (48) United States, the District of Columbia, or a country in which DIGITAL or a subsidiary
of DIGITAL has a software service faCility. The notification must be received by DIGITAL and the system must be ready for
installation within thirty (30) days after the delivery of the SOFTWARE to customer or DIGITAL will have no obligation to
install. Installation will consist of: (1) verification that all components of the SOFTWARE have been received by customer, (2)
loading the SOFTWARE, and (3) executing a DIGITAL sample procedure.
2. During the ninety (90) day period after installation, if the customer encounters a problem with the current unaltered release
of the SOFTWARE which DIGITAL determines to be a defect in the SOFTWARE, DIGITAL will provide the following remedial
service (on site where necessary): (1) if the SOFTWARE is inoperable, apply a temporary correction (TC) or make a
reasonable attempt to develop an emergency by-pass, and (2) assist the customer to prepare a Software Performance
Report (SPR) and submit it to DIGITAl.
3. During the one (1) year period following installation, if the customer encounters a problem with the SOFTWARE which his
diagnosis indicates is caused by a SOFTWARE defect, the customer may submit an SPR to DIGITAl. DIGITAL will respond
to problems reported in SPRs which are caused by defects in the current unaltered release of the SOFTWARE via the
Maintenance Periodical for the SOFTWARE, which reports SPRs received, code corrections, temporary corrections, generally
useful emergency by-passes and/or notice of the availability of corrected code. Software Updates, if any, released by
DIGITAL during the one (1) year period, will be provided to the customer on DIGITAL's standard distribution media as
