Programming With BASIC
General
Information
You can write a BASIC program to perform read and write
operations on your Digital I/O. Before you attempt this,
you should familiarize yourself with controlling the
instrument manually (refer to Chapters 2 and 3). Also, you
must already know how to write programs in BASIC
before you can write your own application program.
Chapter 5 of the System Owner's Manual contains
information about how to develop and run your program.
Before writing your program, you must first use the Soft
Front Panel to create a Program Shell as explained in
Chapter 4 of the System Owner's Manual. You can also
use the Soft Front Panel to assign labels to the Digital I/O
and create one or more State files.
This chapter describes the statements that can be used in
your program to control your Digital I/O, These statements
fall into two categories: system and instrument. System
statements affect other instruments in your system.
Instrument statements only affect the specified (labeled)
Digital Input or Digital Output.
NOTE
If the programming statements in this chapter fail to execute,
you may have a program error. Refer to Chapter 5 in the System.
Owner's Manual which discusses error handling methods.
Appendix C of this manual lists the error messages that apply to
the Digital I/O.
