 7.46 '.include "FILE"'
 ======================
 
 This directive provides a way to include supporting files at specified
 points in your source program.  The code from FILE is assembled as if it
 followed the point of the '.include'; when the end of the included file
 is reached, assembly of the original file continues.  You can control
 the search paths used with the '-I' command-line option (See
 Command-Line Options Invoking.).  Quotation marks are required around
 FILE.
