DESCRIPTION OF FUNCTIONS
VER.V09F
HUNTER Basic understands four kinds of function:
Commands
Statements
Operators
Functions
Commands generally initiate an action and can also control
execution of application programs.
Statements form the structure of application programs and direct
program flow.
Operators are used to relaie data and to test for specified
conditions.
Functions perform arithmetic or string computations.
Some commands and statements ·will function without further
information, others require an argument. An argument is either a
value, an expression or another function.
A complete list of functions is given in section 5.1, INDEX TO
BASIC FUNCTIONS.
