Corrections and Changes Between Versions 3.22 Beta and 3.22:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Date: Monday, 13 May 1996.  Time: 14:20:22.

Summary:  

1)   Implemented numerous FORTRAN source code changes to correct minor errors
     and/or problems that occured during program execution.

     Modified code to correct run-time error in the QUAL2EU model caused when
     a negative value was entered for % (percent) PERTURBATION.  User can now
     enter either a negative or positive value for percent perturbation.
     This value is stored within the DATA TYPE 3 group of the QUAL2E-UNCAS
     first order error analysis data set file (e.g., WTHUAF1.DAT).  Example
     file is listed below with two example DATA TYPE 3 lines (one each
     positive and negative):

UNCAS1   *HEADING            *QUAL2E UNCERTAINTY ANALYSIS; FILE WTHUAF1.DAT
UNCAS2   *SYSTEM TITLE       *WITHLACOOCHEE RIVER (1984); UNCAS/FOEA
UNCAS3   *TYPE OF ANALYSIS   *FIRST ORDER ERROR ANALYSIS; 10     % PERTURBATION
                                     - or -
UNCAS3   *TYPE OF ANALYSIS   *FIRST ORDER ERROR ANALYSIS; -5     % PERTURBATION
UNCAS4   *INPUT CONDITION    *ALL INPUTS
UNCAS5   *INTERMED OUTPUT    *NONE
UNCAS6   *OUTPUT VARIABLES   *HYDRAULIC      QUALITY        INTERNAL
UNCAS7   *OUTPUT LOCATIONS   *    2  2    3 10    7  1   11  5
UNCAS8   *INPUT VARIABLES    *
UNCAS9   *ENDING             *ENDUNCERTAINTY

2)   Recompiled and rebuilt all AIDE library (binary) files (WDMDSN, WDIMEX,
     STATS, WDMRX, UTIL, ADWDM, WAIDE, ANN, WDM, GRAPH, AIDE, NEWAQT) for
     version 3.0x using Lahey FORTRAN 32-bit, protected mode compiler, and
     Phar-lap linker.

3)   Updated the following QUAL2EU model system user support documentation
     files:

     READ.ME........QUAL2EU model system general execution and user support
                    guide
     RELEASE.TXT....QUAL2EU Model System Release Notes
     UPDATE.TXT.....QUAL2EU Model System Update Notes
                    (Enhancements/updates/additions not covered in user
                    manual file)
     ABSTRACT.TXT...QUAL2EU Model System Abstract
     RESPONSE.TXT...CEAM Software Product User Response Form
  
4)   Updated INSTALIT/MediaBuilder code and logic for product version
     description (.PVD) and installation (.INF) script files.

5)   Recompiled and relinked executable task image program files for the
     QUAL2E and QUAL2EU models, version 3.22, and the AQUAL2 and Q2PLOT
     programs, version 1.23, using Lahey FORTRAN 32-bit, protected mode
     compiler and Phar-lap linker.

6)   Included new executable task image files (*.EXE) and updated run
     time support programs and files (.WDM, *.DAT, .SUP, *.LOG).

7)   Included new test output data files DIURNL.OUT, WRKSHOP1.OUT,
     WRKSHOP3.OUT, WRKSHOP2.OUT, WRKSHP2X.OUT, WTHUAF1.OUT, and WTHUAM.OUT to
     test the installation of the QUAL2E and QUAL2EU programs.

8)   Updated the welcome screen file QUALOPEN.SCR.

9)   Updated DOS batch command files (*.BAT) for the execution of the AQUAL2
     and Q2PLOT programs, and the QUAL2E and QUAL2EU models.

10)  Updated Lahey FORTRAN MAKE utility files MAKEFILE[.*] for the AQUAL2 and
     Q2PLOT programs, and the QUAL2E and QUAL2EU model FORTRAN code groups.
