<blockquote>
|
|
<p> A function is defined using the 'Function' keyword: </p>
|
|
<blockquote>
|
|
<p><i>Function {funcname}{typetag}( {params} ) <br>
|
|
{statements} <br>
|
|
End Function </i></p>
|
|
<p>{<b>funcname</b>} is any valid identifier. </p>
|
|
<p> {<b>typetag</b>} is the type of value returned by the function. If {typetag}
|
|
is omitted, the function returns an integer value by default. </p>
|
|
<p> {<b>params</b>} is a comma separated list of variables which is passed
|
|
to the function when it is called, each parameter may be given an optional
|
|
type tag. Parameters are always local. </p>
|
|
</blockquote>
|
|
<p> A function may use the '<b>Return</b>' statement to return a result. Return
|
|
may optionally be followed by an expression. </p>
|
|
<p> If there is no Return statement, or a Return without any expression is used,
|
|
the function returns a default value of 0 for numeric functions, an empty
|
|
string ("") for string functions, or a 'Null' object for custom type functions.
|
