Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     Use the Create Definition File for DLL option to produce a module-
     definition file which can be used if you create a dynamic-link
     library from a .OBJ file. The definition file has the extension
     .DFA and the base name of the project.
 
     This option can be used only if the project consists of a single
     COBOL program. If the project has more than one COBOL program, you
     cannot use this option.
 
     Instead, you should create your own module-definition file using
     the base name of the project and the extension .DFA. For example,
     if the name of the project is TEST, you should create a definition
     file called TEST.DFA.
 
     A definition file used when linking for Animation does not need to
     be specified in the program list.
 
     The module-definition file contains the following lines:
 
          LIBRARY INITINSTANCE
          PROTMODE
          DATA NONSHARED
          EXPORTS entry-point @number
 
     An EXPORTS line is created for the PROGRAM-ID and for each ENTRY
     statement in the program, with <entry-point> representing the name
     of the entry point and <number> a unique ordinal starting at 1.
 
     Command-line directive: DEFFILE"$(PROJ).DFA"
