Some Programming
Techniques
The BASIC built into the Commodore Plus/4, Version 3.5, is the most powerful
and versatile version of BASIC that Commodore has ever used in a computer.
This chapter explains some of the major programming techniques you can use in
writing BASIC programs as well as a few machine language techniques. These
include the following topics:
Using the screen editor
Using the Escape key screen editing functions
Using screen windows
Using text strings
Redefining the function keys
Using mathematical functions
Programming sound and music
Using arrays
UnNEWing programs
Using the built-in error-trapping routines
Each of these topics is covered in a separate section of the chapter. Sample
programs are used to illustrate the use of each technique.
For explanations of all BASIC commands, see Chapter 1. For extensive
information on programming graphics, see Chapter 4. For in-depth descriptions
of commands for handling disk drives and other peripherals, see Chapter 6.
