     Main Output File
 
     LINK can create executable files for DOS or Windows. The kind of
     file produced is determined by the way the source code is compiled
     and the information supplied to LINK. LINK's output is either an
     executable file or a dynamic-link library (DLL).
 
     LINK creates a file according to the following rules:
 
        ■ If a .DEF file is specified, LINK creates a segmented
          executable file. The type is determined by the EXETYPE
          and LIBRARY statements.
 
        ■ If a .DEF file is not specified, LINK creates a DOS program.
 
        ■ If an overlay number is specifed in a SEGMENTS or FUNCTIONS
          statement, LINK creates an overlaid DOS program. This
          overrides a conflicting .DEF file specification.
 
        ■ If /DYNAMIC or /OLDOVERLAY is specified, or if parentheses
          are used in the <objects> field, LINK creates an overlaid DOS
          file. This overrides a conflicting .DEF file specification.
 
        ■ If an object file or library module contains an export
          definition (an EXPDEF record), LINK creates a segmented
          executable file. This overrides an overlay specification.
          The __export keyword creates an EXPDEF record in a C program.
          Microsoft C libraries for protect mode contain EXPDEF
          records, so linking with a protect-mode default library
          creates a segmented executable file.
 
        ■ If an import library is specified, LINK creates a segmented
          executable file.
 
     Map File
 
     LINK can also create a map file that lists the segments in the
     executable file and can list additional information. The /LINE and
     /MAP options control the content of the map file.

     Other Files
 
     The following options cause LINK to produce other output files:
 
        ■ LINK produces a .COM file instead of an .EXE file when the
          /TINY option is specified.
 
        ■ The combination of /CO and /TINY puts debugging information
          into a .DBG file.
 
        ■ A Quick library results when the /Q option is specified.
