+ *                 the line number it occured on.  The reported error message
+ *                 is of the form "....<error_message> on line <line #>.\n".
+ *                 This routine sets error_occured (local to parser.y) to
+ *                 true.  If it was previously false, the error message
+ *                 is reported to the user via stderr.

+ *                 an error is encountered, an error message is printed
+ *                 on stderr and NULL is returned.  If no error is
+ *                 encountered, a pointer to the node representation of
+ *                 the parsed program is returned, suitable for passing to
+ *                 exec.c.  Note that NULL will also be returned for a
+ *                 empty file & is a valid program.  Either way, input_file
+ *                 is closed before this routine returns.
