    5.20 (1998, October):
            All error messages in the Fortran files, previously
              generated by statements like PAUSE 'Error ...', are now
              generated by CALL ERROR('...') in order to enable to fit
              the error handling for a particular computer by editting
              file 'error.for' (the date of subroutines not updated).
            Most warning messages in the Fortran files, previously
              generated by statements like PAUSE 'Warning ...', are now
              generated by CALL WARN('...').
            'ss.for','sp.for': *** Moved from package CRT. ***
            'eigen.for': *** Moved from package NET. ***
            'formsdoc.htm' split into 'formsdoc.htm', 'formsver.htm' and
              'formsdat.htm', list of files moved to 'forms.htm'.
            'forms.for': New subroutines to write and read 3-D data
              cubes for several time levels (4-D data cubes).  Incorrect
              handling of FORMATTED/UNFORMATTED files for lowercase
              arguments of subroutines fixed.
            'length.for': Subroutine LOWER moved from 'sep.for'.
            'sep.for': New subroutines WSEP1, RSEP3Q, WSEP3R and WSEP3I.
              Subroutine WSEPR updated (some reals written in integer
              format).
            'gse.for','grdcal.for','grdpts.for': Some bugs fixed.
            'calcops.inc','srp.for','grdran2d.for': Minor updates.
            'mgrd.for': *** All output grids (data cubes) now written
              into a single file by default, N4 appended to input SEP
              file. ***
            'grdnew.for': *** Input data changed *** (second input SEP
              file discarded).
            'grdran2d.for': *** Input data changed *** (second input SEP
              file discarded, ISEED moved to the SEP file).
            *** new ***
            All MS-DOS batch files '*.bat' and Unix scripts '*'
              replaced by corresponding Perl scripts '*.pl' or by
              history files '*.h' containing the lines specifying how to
              run the programs.
            'error.for': Subroutines to handle errors and warnings.
            'ss.for':
              *** Input data changed to SEP format ***
              Calculating all 3 components within a single run.
              Taking PS filenames from input history file.
              EXTERNAL statements fixed problems with some compilers.
              Some other corrections and updates.
            'sp.for':
              *** Input data changed to SEP format ***
              Overlaying seismograms of several GSE files.
              Plotting all 3 components within a single run.
              Selecting receivers according to the receiver file.
              Taking PS filenames from input history file.
              Some other corrections and updates.
            'calcops.for': New entry PLOTN enables to specify the name
              of the output PostScript file.  Now, spaces plotted by
              subroutine SYMBOL are not included into the bounding box.
            'grdcal.for': Updated from 3-D to 4-D data cubes.  3-D data
              cubes may be also be used for 4-D calculations.  Values of
              constants may now be taken from the input SEP parameter
              file.  Conversion to integer data cubes introduced.
            'grdfd.for', 'grdnorm.for': New programs.
            'grdps.for': Considerable revisions:  Updated from 3-D to
              4-D data cubes (snaphot generation).  Multiple input data
              cubes may now be displayed in the same figure (e.g.,
              colours from the first data file and shades from the
              other data file).  Various length units (cm,in,pt)
              enabled to facilitate bitmap generation.
              *** Input data changed. ***
            'sep.pl', 'forms.pl', 'go.pl', 'echo.pl', 'append.pl',
            'chk.pl', 'compdel.pl': New programs and subroutines
              coded in Perl.
