   2.4    02/06/26  Revised text in statistical summary output.  Added calls
                    to check pointers in a WDM file when it is opened and
                    when it is closed.  Compiled using updated libraries:
                    version 11.1 of libhsp and version 4.0 of libanne.

                    There were several changes made in the statistical
                    summary.  "Total annual runoff' has been changed to
                    "Total runoff"; this value is for the entire simulation
                    period as defined in the UCI file.  "simulated storm"
                    has been deleted from "Total simulated storm interflow"
                    and "Total simulates storm surface runoff"; the values
                    are totals for the entire simulation period as defined
                    in the UCI file, not for the storm periods defined in 
                    the EXS file.  "Error in storm volumes" has been changed
                    to "Error in storm peaks"; this value is calculated
                    from peaks, not volumes. (hsxout.f and hsxout.seq)

                    Added call to WDMCHK to check pointers in a WDM file
                    after it is opened (hsxbas.f).  Added call to WDFLCL
                    to close WDM file and check pointers before exiting the
                    program (hspexp.f).  Both of these routines are from
                    libanne.  If you have had problems with WDM files being
                    corrupted, this should help you identify the cause.

                    A dimension in the hspf library was increased to allow
                    all of the RCHRES quality parameters to be included in 
                    a simulation.  As hspexp is generally not used for
                    water quality simulations, this should not have been
                    a problem in the past and should have no impact.

                    hspexp was previously compiled using version 3.0 of
                    the lib library.  The lib library which had contained
                    the hspf, wdm, statistics, and utility libraries has
                    been divided into two libraries, libhsp and libanne.
                    libhsp contains the hspf source code.  libanne
                    contains the wdm, statistics, and utility code.
                    
   2.3    95/03/30  Correction made in hspf simulation of evapotranspiration.

                    There was a problem in subroutine ETLZON with the check
                    to see if there was enough storage in the lower zone
                    to meet the potential.  If not, LZET had been set to
                    the current lower zone storage (LZS), completely emptying
                    the storage, causing an underflow to occur in subroutine
                    SURFAC.  The code was modified to set LZET to
                    LZS - 0.02, leaving a small amount in storage.

                    Code group lib2.0/src/hspf/hperwat.f was modified.

          95/09/07  Some utilities in hspexp have been moved to newaqt.
                    These utilities were made more generic.  hspexp has
                    been modified to use these utilities from the library,
                    some changes in the code were required to interface
                    with these utilities.

          95/11/28  Corrections made in the hunting.uci files in data/huntday
                    and data/hunthour.  In MASS-LINK 91, IWATER PET should go
                    to COPY MEAN 4 (not 5) and IWATER IMPEV should go to COPY
                    MEAN 5 (not 6).

                    NOTE that in printed copies of the hspexp user's manual,
                    page 23., has the wrong values in the example.  This has
                    been corrected in the electronic version.

          96/03/01  Modified subroutine ucirea to resolve problems opening
                    files identified in a uci file.  Code now checks to
                    see if a file is already open, file is closed if
                    it is open and then re-opened.  Problems had been
                    encountered with Fortran 90 compilers that objected
                    to opening an already open file.  The problem was
                    only apparent in program hspexp.

   2.2    94/08/19  Miscellaneous changes and editorial cleanups.

                    Format of print file modified slightly to be consistent
                    with format on the screen.

                    Changes were made to show the statistics for peak flow
                    in cfs for each storm instead of the volume of the highest
                    day for each storm.



   2.1    94/07/07  Miscellaneous corrections and enhancements.

                    Increase number of data points that can be plotted, can
                    now plot 5 time series for 7 days at 5-minute time step.

                    Change made to correctly sum precipitation for time series
                    plots.
