!
!                     RMAGEN Version 4.2
!       
!                   Release date   Jan 13 1998
!
!
! Changes in this version include:
! (1)  Revisions to operate in a graphical mode, reducing the amount of
!      DOS screen input.
! (2)  Addition of options for both the node move operation and refine 
!      options to allow the user to stop preservation or automatic 
!      interpolation of bottom elevations from the corner node values.
!      This option is a user setting.  The default initial setting 
!      retains the value for the move operation and interpolaton during
!      refinement.
! (3)  Input of "geo" has been made more flexible.  The model 
!      automatically detects binary files with and without headers.  Note
!      that this option is only relevant for PC versions.
! (4)  The screen now displays compilation limits on startup.
! 
!
!                     RMAGEN Version 4.1(a)
!       
!                   Release date   Nov 18 1997
!
!
!
! Changes in this version include:
! (1)  Revised interpolation scheme for computing bottom elevations from
!      map file data.
! (2)  More consistent backup
! (3)  Addition of option to split triangles when refining
!
!                     RMAGEN Version 4.1
!
!                   Release date   Oct 19 1996
 
! Changes in this version include:
! (1)  New options that allow selective drawing of maps in different
!      colours
! (2)  An option that allows construction of continuity lines from the 
!      map screen
 
!                     RMAGEN Version 3.3
 
!                   Release date   April 1 1994
 
! Changes in this version include:
! (1) Incorporation of the ability to record and play scripts.
! (2) Correction to correctly operate in the top half inch of the network
 
!                     RMAGEN Version 3.2
 
!                   Release date   March 1 1994
 
! Changes in this version include:
! (1) Modification to the save options to enter a menu of save choices.
! (2) Addition of the capability to save a binary version of the map file.
! (3) Correction to the "backup file" to make it work consistently.
! (4) Changes to the algorithm of the bottom elevation generation routine
!     to improve reliability.
! (5) Removal of an implied limitation of 32000 lines for the map file by
!     deleting some INTEGER*2 variable to INTEGER*4.
 
!                    RMAGEN Version 3.1(a)
  
!                   Release date   Aug 1 1993
 
! Changes in this version include:
! (1) Correction to colurs that make them more readable.
! (2) Additions to the SELECT options that permit more flexible choice
!     of elements.
 
!                     RMAGEN Version 3.1 
 
!                   Release date   March 1 1993
 
! Changes in this version include:
! (1) Correction in fill operation to ensure correct fill when there are
!     a number of gaps in the nodal sequence.
! (2) Additions to the NODE-DELETE options that permit more flexible 
!     deletion options such as all mid-side nodes, all exact mid-side
!     location nodes or all unused nodes.  The fill option has added
!     flexibility.
 
 
!         Version 3.0(c)  August 1 1992
 
! Changes in this version include:
! (1) Revisions to incorporate REGIS graphics capability
! (2) Block of routines available to use DEC 340 REGIS graphics
!     terminal with unix system
 
 
!         Version 3.0(b)  May 20 1992
 
!   Changes in this version include:
!   (1) Renaming of all colours for compatibility with Silicon Graphics
!   (2) Modification of nodal delete so that when a mid-side node is 
!       selected for deletion it is removed and the associated reference
!       in the element is set to zero.  The element is no longer deleted.
!   (3) Cleanup of array subscripts in SUBROUTINE HEDRC
 
!         Version 3.0(a) April 1992
 
!         Changes to a number of routines to correct minor errors
!         and nuisances.
 
!         Version 3.0   January 1992
 
!         This version revises the naming of input and output files.
!         Output files may be generated in ASCII or BINARY form.
!         The binary file is designed to bypass RMA-1.
!         This file optionally may contain element reordering numbers
!         New capabilities include:
!         (1)   Automatic filling of zero's in element connection arrays.
!         (2)   Input of reordering sequences and executing the reordering
!               process.
