-export template<pint W, V> defproc source (chan!(int<W>) O);
+template<pint W, V>
+defproc source (chan!(int<W>) O);
 </code>
 This creates a data source that has bit-width ''W'', and that repeatedly sends the constant value ''V'' on the output port ''O''.
 <code act>
-export template<pbool LOG; pint W> defproc sink(chan?(int<W>) I);
+template<pbool LOG; pint W>
+defproc sink(chan?(int<W>) I);
 </code>
 This process acts as a data sink; it repeatedly receives ''W''-bit input on the input port ''I''. If the ''LOG'' parameter is set to true, then it also displays the value received using the ''log()'' command.
 <code act>
-export template<pint W; pbool REP; pint N; pint data[N]>
+template<pint W; pbool REP; pint N; pint data[N]>
 defproc source_seq(chan!(int<W>) O);
 </code>
+This process also provides a ''W''-bit source. Values generated by this source are specified in the ''N''-entry ''data[]'' array. The outputs produced are ''data[0]'', ''data[1]'', ..., ''data[N-1]''. If ''REP'' is set to true, then this sequence is repeated forever.
+<code act>
+export template<pint ID; pbool LOOP; pint W>
+defproc file_source(chan!(int<W>) O);
+</code>
+This process is also a ''W''-bit source, except the values produced are taken from a file. The identified ''ID'' is used to determine the file name, and the file is assumed to have at least one data value. By default, the file name is ''_infile_.{ID}''. The file format is a sequence of hexadecimal values, one per line. If ''LOOP'' is set to true, then the sequence of values specified in the file is repeated forever.
