-===== Freefile (Function) =====
-==== Format ====
-**freefile**\\
-**freefile** ( )
-returns [[integerexpressions|integer_expression]]
-==== Description ====
-BASIC256 allows for multiple files to be opened at a single time.  The **freefile** function returns a free [[integerexpressions|open_file_number]] that you can use in your next [[Open|Open]] or [[Open|Openb]].  Once a file is closed, **freefile** will return that [[integerexpressions|open_file_number]] to the list of available file numbers and may reissue that number.
-==== Example ====
-<code># copy one binary file to another
-k = 0
-source = freefile
-openb source,"file.pdf"
-dest = freefile
-openb dest,"file_copy.pdf"
-reset dest
-while not eof(source)
-   writebyte dest, readbyte(source)
-   k++
-end while
-close dest
-close source
-print k + " bytes copied."
-</code>
