'''FileID'''

A FileID is an identifier associated with a certain [[file]] (FPG). It is returned by [[load_fpg]](), when a file is loaded to memory and can be used in many [[function]]s, wanting a FileID, for example [[map_put]]() or [[start_scroll]](). A FileID can also be assigned to the [[local variable]] [[file]] of a [[process]] or function, which will make the process in question look in that file (FPG) for the [[graphic]], associated with the [[GraphID]] specified by the process' [[graph]] local variable.

== Example ==
<pre>
Program files;
Global
int file_id;
Begin

// Load FPG
file_id = load_fpg("example.fpg");

// Set locals for display of graph
file = file_id;
graph = 1;
x = y = 50;

Repeat
frame;
Until(key(_frame))

End
</pre>
Used in example: [[load_fpg]](), [[key]](), [[file]], [[graph]]
