Functions are the most powerful building blocks.

<BR><BR>

Every program that use save (".fpp" file) is a function, you can call it from
any other algorithm or even from itself (recursion). To add function use "func"
button. Type function filename (without extension!) in function name field.

<BR>

You can set local variables (useful for recursion) by editing the "start" block.

<BR><BR>


There are also several built-in functions:<BR>
<B>Fix</B> - receives a number, returns fixed number (without digits after the dot).<BR>
<B>FileDialog</B> - opens a file dialog.<BR>
<B>Clear</B> - clears the user text screen.<BR>
<B>ExtractFileName</B> - receives full file path, returns only the file name.<BR>


<BR><BR>

Both function algorithm and the caller algorithm should be saved in the same folder.

<BR><BR>

Functions can also be specified for window events.
