	AUTOCLASS C VERSION 3.3 NOTES 
====================================================================== 
======================================================================

NOTE: This version is an integrated source port of version 3.2.2 to
      Windows NT/95.  There are no new capabilities or bug fixes over
      and above version 3.2.2.

Windows Compatibility Changes:
-----------------------------------
  Thanks to Autumn <autumn@netron.com>, we now have an integrated
  source release of AutoClass C for Unix platforms and Windows
  platforms (requires Microsoft Visual C++ 5.0).  Due to the Unix
  "line feed" and the Windows "carriage return/line feed" incompatibility,
  there are two distributions, one for Unix-based platforms, and one
  for Windows platforms.

  Summary of source changes:
     autoclass-c/prog/*.c -
        Using _MSC_VER in preprocessor forms, remove the include of
        Unix-specific headers, and add the Win32 equivalent.
     autoclass-c/prog/autoclass.h -
        Use rand in place of lrand48, therefore change srand48 to srand.
     autoclass-c/prog/getparams.c, getparams.h, intf-reports.c, search-control.c
        Prefixed enum members with T so they would not clash with predefined types.
     autoclass-c/prog/init.c
        getcwd is called _getcwd in MSVC.
     autoclass-c/prog/model-expander-3.c, params.h, struct-class.c -
        Prefixed enum member IGNORE with T so it would not clash with
        predefined type.
     autoclass-c/prog/search-control.c -
        Made two queries conditional on interactive_p; moved init of stream
        with stdout -- MSVC doesn't think it's a constant.
     autoclass-c/prog/utils.c -
        Created an lrand48 for win32; created a char_input_test() that works
        with win32.
     autoclass-c/prog/fcntlcom-ac.h -
        Adapt for MSVC.


Documentation:
------------------------------

  1. Update sample AutoClass C run files contained in autoclass-c/sample.


Programming:
------------------------------						

  1. autoclass-c/prog/globals.c -

     Update "G_ac_version" to 3.3unx or 3.3win, depending on which
     platform AutoClass C is compiled.

  2. autoclass-c/prog/globals.c, globals.h, intf-extensions.c, intf-reports.c,
       search-control-2.c, search-control.c, io-results-bin.c,
       io-results.c, io-read-model.c, & io-read-data.c -

     Add G_slash, which is "/" for Unix, and "\" for Windows.
     Change all occurrences of local variable "slash" to "G_slash".
     This will allow AutoClass C to handle both Unix and Windows
     relative and absolute pathnames properly.

  3. autoclass-c/prog/init.c -

     In INIT, append either "/" or "\" to G_absolute_pathname.

  4. autoclass-c/prog/intf-sigma-contours.c -

     In GENERATE_SIGMA_CONTOURS use %+13e for Windows instead of
     %13e in order to maintain column alignment for positive and
     negative values.

  5. autoclass-c/prog/intf-reports.c -

     For Windows, use %+9.2e rather than %9.2 in FORMAT_REAL_ATTRIBUTE
     and FORMAT_DISCRETE_ATTRIBUTE, in order to maintain column alignment
     for positive and negative values.

     Call FILTER_E_FORMAT_EXPONENTS to filter Windows peculiar %e format
     output of e+000 => e+00, and e-000 => e-00.

  6. autoclass-c/prog/intf-sigma-contours.c -

     For Windows, use %+13e rather than %13 in GENERATE_SIGMA_CONTOURS,
     in order to maintain column alignment for positive and negative values.

     Call FILTER_E_FORMAT_EXPONENTS to filter Windows peculiar %e format
     output of e+000 => e+00, etc, and e-000 => e-00.
     

  7. autoclass-c/prog/io-results.c, io-results-bin.c -

     In READ_CLSF_SEQ and LOAD_CLSF_SEQ, truncate unx/win from the version
     prior to checking for numeric content.

  8. autoclass-c/prog/autoclass.c -
     In AUTOCLASS_ARGS, display "autoclass" or "Autoclass.exe" depending
     on platform.
