This disk contains the sources and other information to construct
this program.  The files and their functions are listed below:

          README.1ST    This file
          ABSTRCT.TXT   Program description for publication
          ERROR.FTN     Routines to generate error messages
          GETCDS.FTN    Routine to prompt for a file name
          QIOSYM.FTN    Routine to read error message file
          RHP.FTN       Main program and other subroutines
          GCML.MAC      Fortran callable GCML
          LENGTH.MAC    Routine to get length of string
          POS.MAC       Routine to find position of string in string
          RHP.TSK       Compiled program
          RHP.CMD       Command file to build the program
          RHP.DOC       User documentation
          TEST.RGS      Test file of ReGIS commands

Two additional DEC-supplied files are required: QIOSYM.MSG, which
should be in directory LB:[1,2], and IECIO.FTN (supplied with the
IEC-11 driver), which should be in directory LB:[1,1].  If these
files are in other directories, edit the source files appropriately
(QIOSYM.FTN or RHP.FTN respectively).

The driving of the plotter is all carried out through the subroutine
IEEE (entry points IEEINI, IEEWRT and IEEEXI) in RHP.FTN.  Note that
an HPIB address of 9 for the computer and 31 (i.e. listen only) for
the plotter are assumed.  To change the computer address, change
parameter COMADR in routine IEEE (in file RHP.FTN).  To use a different
interface (e.g. RS232), only this routine need be changed.
