PREFACE
This manual describes and explains the features and conventions
of
Intel Disk Ex-
tended
BASIC-80, as implemented on Intel Intellec
microcomp~ter
development
systems using the Intel
Systems Implementation Supervisor (ISIS-II), and on Intel
Single Board Computer Systems using the Intel Real-Time Multitasking Executive
(RMX-80).
This manual
is
written for users who require concise, complete information about
Intel
BASIC-80 characteristics, and organizes this information into seven chapters
and five appendices;
"Introduction" describes the general capabilities of BASIC-80, and its operating en-
vironment.
"Language Elements" describes the ways BASIC-80 represents its instructions, con-
stants, variables, arrays,
operators, and expressions.
"Entering and Editing Programs" shows how you enter text and edit it, at time
of
entry or after storage.
"Error
Handling" shows how errors are identified, trapped, and used to initiate
error-resolving routines.
"Disk File
Input/Output"
describes and sh0ws how random and sequential data
files
are created and used.
"Commands and Statements" describes each command and
statem~nt
in alphabetic
order.
"Functions" describes each function in alphabetic order.
"Appendix
A:
BASIC-80 Error Codes" lists all BASIC-80 error messages, descrip-
tions, and codes in tabular format.
"Appendix
B:
BASIC-80 Reserved Words" lists words that cannot be used in
variable names.
"Appendix C: BASIC-80 Command Characters" lists BASIC-80 one-character
editing and control characters and their meanings.
"Appendix D:
ASCII Codes" lists ASCII codes and their meanings.
"Appendix E: Calling Non-BASIC-80 Subroutines" shows how to prepare and call
PL/M-80, FORTRAN-80, and 8080/S085 assembly language subroutines.
"Appendix F: Configuring RMX-80 BASIC-80" shows how to configure BASIC-80
with various hardware systems using
RMX-SO.
