Using BASIC Module Statements
This chapter groups the statements and calls required to manipulate the
various hardware parts of the BASIC module. We assume you are familiar
with standard BASIC programming practices. Therefore, standard BASIC
commands and statements are not covered here unless a special
consideration is required for the BASIC module. Some calls perform
multiple operations and are listed in more than one place. Chapter 11
describes the statements in detail and Chapters 12 and 13 describe the calls
in detail.
