Programmers' Guide
The following information is included to help you adapt this software for use with your own card
reader application. Chapter 4 of this manual contains complete information on the commands
recognized by the CR-510.
The files that are included on the enclosed diskettes are listed and described below. Some guidelines
for using these drivers with your own applications are also given.

Source file for Assembly language
driver.
Object file for Assembly language
driver. This file is in "Dump" format as
required by COBOL—that is, it was
created using the TRSDOS DUMP
command.
Object file for Assembly language
driver.
BASIC Program that calls the Assembly
language driver, handles user input,
and prints output to the screen.
Annotated versions of BCR64 and
BCR48. The purposes of the various
routines in the program are described.
Differences in the 32K program are
noted.
"DO" files to initialize the RS-232 port,
load the Assembly language driver, set
top of memory, and execute the
BASIC card reader software.
Source file for the COBOL program
that calls the Assembly language driver,
handles user input, and prints output
to the screen. Comments explaining the
various sections of the Procedure
Division are included.
Object file for CCRxx/CBL.
"DO" files to initialize the RS-232 port,
load the assembly language driver, set
top of memory and execute the
COBOL card reader software.
(*) Listings of the files marked with an asterisk appear at the end of this section.
First, you should familiarize yourself with the annotated versions of the files for your model number
and memory size TRS-80 computer (BCRNOTES, CCR/CBL, CCR32/CBL, or CCR48/CBL).
The Assembly language program is a general purpose driver for the CR-510. It can be used with
cards in any format. If your application uses 40 column general purpose cards, like those included
with this CR-510, then the BASIC and COBOL programs can be used as they are. The information
returned by the card reader to the TRS-80 microcomputer is contained in "A$" in the BASIC
program, or in "COLS" in the COBOL program (see annotated version for details). These
