SUMMARY
=======

Beginning with version 5.3, the Microsoft Segmented Executable Linker can create
executable files for three different operating systems: MS-DOS, Microsoft
Windows, and OS/2. LINK determines the executable file type (EXETYPE) unless it
is specified explicitly in the module- definition (.DEF) file. The EXETYPE
defaults to a different type depending on the host operating system, the
presence of the .DEF file, and the presence of imported or exported symbols. The
following chart summarizes the default EXETYPE values:

--------------------------------------------------------------------
|Host Operating | No .DEF File | .DEF File |Imports/Exports in Module|
|   System      |   Present    |  Present  |and No .DEF File Present |
--------------------------------------------------------------------
|               |              |           |                         |
|    MS-DOS     |     MS-DOS   |  Windows  |          MS-DOS         |
|               |              |           |                         |
--------------------------------------------------------------------
|               |              |           |                         |
|     OS/2      |     OS/2     |  Windows  |           OS/2          |
|               |              |           |                         |
--------------------------------------------------------------------

In previous versions of the Segmented Executable linker, OS/2 is the default
EXETYPE when a .DEF file is present.

MORE INFORMATION
================

EXETYPE [<descriptor>] statement specifies the target operating system
with which an application is designed to run. The <descriptor> value can
be one of the following values:

  Descriptor           Meaning
  -------------------------------------------------------------------
WINDOWS [<version>]  Microsoft Windows. Default EXETYPE value. The
                       <version> parameter specifies the minimum
                       version of Windows needed to load the
                       application or dynamic-link library (DLL). The
                       syntax for <version> is as follows:

                          <number>[.[<number>]]

                       where each <number> is a decimal integer.

  DOS                  Nonsegmented executable file. LINK assumes
                       EXETYPE DOS for an overlaid MS-DOS program.

  OS/2                 OS/2 version 1.x segmented executable file.

  UNKNOWN              Other applications.
