The INCLUDE (abbreviated INC) command copies external files into text
 buffers.

 Format: INCLUDE file-spec [range]

 The specified file is copied to the location before the first line of
 the range. Note that range specifies the position to which the file will
 be copied; it does not restrict the portion of the file which will be
 included.  To include part of a file, first INCLUDE the file into a
 buffer; then COPY the desired portion of the included text into the
 appropriate buffer.
