FT_FAPPEND()
 Appends a line to the currently selected text file
------------------------------------------------------------------------------

 Syntax

      FT_FAPPEND( [ < nLines > ] ) -> NIL

 Arguments

     <nLines> is the number of lines that should be appended to the
     end of the currently selected text file.

     If <nLines> is omitted, one record is appended.

 Returns

     NIL

 Description

     This function appends a line of text to the file in the currently
     selected text file workarea.  Text lines are delimited with a
     CRLF pair.  The record pointer is moved to the last appended
     record.

     Multiple lines may be appended with one call to FT_FAPPEND().

     A text file "record" is a line of text terminated by a CRLF pair.
     Each line appended with this function will be empty.

     NOTE:  Occasionally a text file may contain a non-CRLF terminated
     line, at the end of the file ("stragglers").  This function assumes
     these stragglers to be the last line of the file, and begins
     appending the new lines after this line.  In other words, if the
     last line in the text file is not terminated with a CRLF pair prior
     to calling FT_FAPPEND(), the function will terminate that last line
     before appending any new lines.

 Examples

     // add a blank line of text to a file
     FT_FUSE( "test.txt" )

     ?FT_FRECNO()           // displays 5

     FT_FAPPEND()

     ?FT_FRECNO()           // displays 6
