APPENDIX F RMX/SO BASIC-SO This appendix describes the differences between the
RMX/SO
version
of
BASIC-SO
and the ISIS-II version,
and
tells you the requirements and procedures for
generating disk-based or ROM-based versions
of
RMX/SO
BASIC-SO.
It
is
recom-
mended that you refer to the
RMX/SO
User's Guide and RMX/SO Installation
Guide for supplementary information.
What
is
RMX/80
BASIC·80?
The
RMX/SO
BASIC-SO Interpreter (iSBC
S02)
runs under the
RMX/SO
Real-Time
Multi-Tasking Executive. With
RMX/SO
BASIC-SO, you can easily use the powerful
computational
and
input!
output capabilities of the iSBC/SO Microcomputer
System, and apply them to solving a wide range
of
application problems.
The iSBC
S02
software package gives you
RMX/SO
BASIC-SO
in two forms. First,
BASIC-SO modules, coded to run as tasks under RMX/SO, are supplied on both
single- and double-density diskettes. You can edit these modules with the ISIS-II
Text Editor or CREDIT, and combine them with
RMX/SO
and user application
tasks. You use the Intellec Development System to create a version
of
RMX/SO
BASIC-SO
tailor-made for your iSBC-based microcomputer system.
This first ("configure your
own")
option requires you to have a copy
of
the
RMX/SO
software and be familiar with its use. The portions of this appendix that
describe how to configure your own
RMX/SO
BASIC-SO
system will therefore make
frequent references to the following publications:
RMX/SO User's Guide, manual order no. 9S00522
RMX/SO Installation Guide, manual order no.
9S030S7-01
Second, if you want
an
"instant-on" BASIC-SO system, and have no need for addi-
tional software routines, you can use the predefined
RMX/SO
BASIC-SO
configura-
tion. This configuration includes three parts:
• The executable object module RMXSYS, supplied on both the single and double
density diskettes.
• Two boot strap PROMs that load RMXSYS into the iSBC memory.
• A cable that connects the iSBC 204 disk controller to the bulkhead connector
on
any Intellec disk drive chassis.
With this predefined version, you have a version
of
RMX/SO
that
appears on
RESTART on your iSBC hardware configuration. You need only make the
necessary hardware connections, and
BASIC-SO
is
ready to run.
You should be aware
of
the major differences between
RMX/SO
based BASIC-SO
and ISIS-II based BASIC-SO. These are:
• Configuring the
RMX/SO
modules determines how much memory will be
available to the BASIC-SO interpreter and the program source. The sample con-
figuration provides S.4K bytes
of
memory space.
• You must also specify the number
of
files available to BASIC-SO when you
configure the
RMX/SO
modules. The sample configuration supports 6 open
files
at
once.
