Command/Function NAME

The Format section explains how the command is arranged and its parameters. For example, the

AUTONUM

command starts the auto-numbering option. The format for the command is

AUTONUM <A>

,

<B>

. The

<A>

and

<B>

are parameters of this command and are replaced with values determined by the user.

For functions, parameters are enclosed within parentheses and separated by commas, such as

EXTRACT$(A$,START$,STOP$).

Numeric parameters are written as a name, while string parameters are written as a name followed by a dollar sign.

If a command has parameters that make a command or function more specific, they are listed under this heading. Still using the

AUTONUM

example, the

<A>

parameter is defined as:

<A>

= number used to start the auto-numbering sequence

The return value is the result of evaluating the function or expression.

When a command is best clarified in a programming context, an example of the ZBI code is provided. Text indicating parameters, exact code to be entered, or data returned from the host is printed in the

Courier

font to be easily recognizable.

An example of

PRINT

code is:
