     ABSTRACT.TXT, TERM_DAT.TXT, and/or RESPONSE.TXT.

2)   Composed new INSTALIT/MediaBuilder code and logic.  Upgraded INSTALIT/
     MediaBuilder product version description and INF script files from
     version 3.19c to version 5.03d.  Implemented numerous code changes to
     correct minor problems and add features/enhancements.

3)   Recompiled and relinked PRZM2 library using Lahey FORTRAN 32-bit,
     protected mode compiler, Phar-lap linker, and AIDE WDM, UTIL, and ADWDM
     libraries.  Eliminated the need for Interacter graphics libraries during
     the PRZM2 model link step.  Updated, recompiled, and rebuilt all AIDE
     library (binary) files (*.LIB) from version 2.0x to version 3.0x.

4)   Recompiled and relinked PATRIOT model using Lahey FORTRAN 32-bit,
     protected mode compiler, Phar-lap linker, and AIDE WDM, UTIL, ADWDM,
     AIDE, WAIDE, GRAPH, NEWAQT, ANN, STATS, and PRZM2 libraries.  Updated,
     recompiled, and rebuilt all AIDE library (binary) files (*.LIB) from
     version 2.0x to version 3.0x.

5)   Included new executable task image file (*.EXE) and all updated run time
     support programs and files, including unformatted, direct access data
     and water shed data management files (*.DAT, *.WDM).

6)   Implemented numerous FORTRAN source code changes to correct minor errors
     and/or problems that occured during program and/or model execution and
     added new features/enhancements.

7)   Added interactive test log (*.LOG) and ASCII text files containing key
     stroke command sequences that match the log files.

8)   Increased the number of pesticide applications from 400 to 600 for PRZM2
     version 2.01.
