Release Notes for

               Compaq KAP Fortran/OpenMP Version 4.2 for Tru84 UNIX
                                  September 1999



          1  Purpose of Release Notes

          These release notes provide information about this version of
          KAP Fortran software and user documentation. Please read
          them before using the product.

          The distribution kit (KF9BASE420) includes both the KAP Fortran
          77 and KAP Fortran 90 software. A license for either product
          allows execution of both products.

          This version has been tested with Tru64 UNIX Version 4.0D, 4.0F,
          5.0 and Fortran90 V5.2 or later.

          To identify the version of KAP translators on your system, look
          at the first part of the software's output to the terminal.
          Three consecutive fields contain a version number, baselevel, and
          date in YYMMDD format. For Version 4.2 these fields contain:

          4.2 k3105107 990825 (for kf90/kapf90)
          4.1 k310561 981107 (for kf77/kapf77)

          2  Changes to kf90 and kapf90 since previous version

          This is a maintenance release. We have made no changes to the 
          kapf77 or kf77 products.

          Version 4.2 includes fixes to problems in the following areas:

		- Parsing OpenMP directives on input and generating OpenMP 
                  directives.

		- Parsing Fortran-95 syntax.

		- Support of HPF directives and intrinsics. 

		- Optimization of subscript references to the LBOUND
                  and UBOUND intrinsics during inlining of array intrinsics.

                - Change of the default cache-size and set-associativity when
                  "-tune=ev6" as follows:

                     Old values for "-tune=ev6":

                     -chs=64,64 -sasc=2

                     New values for "-tune=ev6":

                     -chs=32,0 -sasc=1

                     where "-chs" is an acronym for cache-size and "-sasc" 
                     is an acronym for set-associativity.

                  The default values for -tune=ev4 or -tune=ev5 have not
                  changed.

                - Deadcoding of functions via interprocedural analysis has
                  been corrected. An example for this type of problem is the
                  "lucas" benchmark in the CPU-2000 performance suite.

                - Specifying long lists of files via the "kf90" driver 
                  sometimes caused extraneous ctrl-b characters to be inserted
                  in the call to the Fortran-90 compiler. This has been fixed.
                  An example of this is the "fma3d" benchmark in the CPU-2000
                  performance suite.


          3  Known Problems

          The error message returned when your threaded application has
          run out of stack space has changed. The DIGITAL UNIX Version
          4.* message is something like:

                DECthreads Last Chance handler: thread 1 exiting on status
                            exception 0x177db005
                         Exception: Invalid memory address (dce / thd)

          If this happens, try unlimiting your process quotas using the
          csh unlimit command.
