User-Defined
Functions
Introduction
In addition
to
the built-in functions described
in
the
tWO
previous
sections,
TI BASIC provides user-defined functions. User-defined
functions
can
simplify programming by avoiding
repeated
use of
complicated expressions. Once a function has been defined using
the
DEF
statement. it may be used anywhere
in
the program by
referencing the
name
you gave to the function.
