The three subdirectories [.DOCUMENT], [.GPLOT], [.MODIFY] contain routines
from the Intense Pulsed Neutron Source Division of Argonne National
Laboratory. 

MODIFY was described in an article in the VAX Professional, December, 1987.

GPLOT is being described in session G055 at the 1988 Spring DECUS Meeting. 

Both the GPLOT and MODIFY subdirectories contain named SYSMAN.* which are
MASS11 documents which will allow those with MASS11 word processing to
generate their own hard copies of these documents. 

DOCUMENT is a small command written to extract documentation from source
files documented in accordance with the DEC Guide to Creating Modular
Procedures on VAX/VMS.  The GPLOT subdirectory contains GPLOT.DOC which was 
created from the directory containing the source code for GPLOT.  
Unfortunately, many of the routines were written before we decided to 
comment them according to the DEC Guide, so no documentation was extracted.

ADDCOMMAND.COM can be used to add MODIFY and DOCUMENT to your system 
command table.

GPLOT is a library of high-level graphics routines to simplify and enhance
the use of DEC VAX GKS.  These have been tested with VAX GKS 3.0. The GPLOT
subdirectory contains a number of graphics example routines and contains
the source to those routines which might need to be customized for a
particular site.  GPLOT was originally written to ease the conversion of
graphics codes from CA-DISSPLA to DEC VAX GKS.  The DISSPLA emulation
routines included are based on what we had been using at IPNS.  Others will
be added as the need arises, and some of the clumsy features (caused by the
lack of character string support in the older versions of Fortran) will be
eliminated when we obtain version 11.0 of DISSPLA.  Future enhancements to
GPLOT will not in general follow the DISSPLA example. 

The library TOOLS.OLB was included because MODIFY calls some of those routines
for screen control, etc.

Please let me know about bugs found in these routines.  Source for other 
routines in these libraries can be provided if needed.
