XREF27.ASM  Cross-reference program for .ASM or .PRN files 11/09/85


  This program generates a cross-reference list for all labels in an
  .ASM, .MAC or .PRN file.  Thus it works with either an assembly level
  source code file or an assembled print file.	No other cross-reference
  program is known to have this sort of versatility and ease of use.  It
  will number the lines and generate a cross-reference listing at the
  end of the program.  If a numbered listing is not requested, it makes
  a cross-reference listing without the source code - this is often used
  to find what label names have been already used - or which labels were
  actually unnecessary as they were not used at all.  The output can be
  shown to the CRT, sent directly to the printer, or to a disk file.  If
  a disk file is used, it is given the same name as the original file,
  with an .EXR extent.

  11/09/85  Fixed an intermittent bug that was causing the program to
    v27     miss seeing the EOF character and keep right on going until
	    it bombed by filling the disk.  This occured on some longer
	    .PRN files when adding line numbers.  Took awhile to find,
	    as only occured occasionally.  Likely been around since the
	    program was written.	- Irv Hoff

  It is invoked by entering:

	XREF FILEBNME.ASM	(output to printer)
	XREF FILENAME.PRN CRT	(output to CRT)
	XREF FILENAME.ASM D	(output to disk - default drive)
	XREF FILENAME.PRN B:D	(output to disk - drive B: in this case)

  To get the help guide type:

	XREF ? <ret>  or   XREF <ret>
