5/ Using the Card Reader
Demonstration Software
A Model III diskettte and a Model II diskette accompany this package. Each diskette contains a
demonstration in BASIC and a demonstration in COBOL of the software components used to read
cards. Use of these programs is outlined below.
Running a Demonstration
BASIC Card Reader Program When the message "TRSDOS Ready" appears:
You'll then see a series of initializing messages. Next, you'll see a paragraph that introduces the
demonstration. Read the paragraph. Below it, the message:
will appear.
You will see the series of prompting messages that were described above under "BASIC Card Reader
Program." The only apparent difference between the way the BASIC and the COBOL programs
run is that the COBOL program reads cards much faster.
To run the COBOL demonstration program, you need the COBOL Run-Time diskette (Model II,
26-4704; Model III, 26-2207). If you have a two-drive system, place the Card Reader Demonstration
Software diskette in Drive 0 and the COBOL Run-Time diskette in Drive 1. If you have a single-
drive system, copy the following Card Reader Software files onto their Run-Time diskette, as specified
for the computer you're using:
