Developer: My Application Uses Assembler Support

You can include Assembler modules in your COBOL or PL/I projects. You can edit Assembler source code, compile and link the code including copybooks and macros provided with Enterprise Developer, or ones you have written yourself, trace and debug your Assembler modules.

The following steps provide guidance on how to create mainframe projects in Enterprise Developer for your COBOL and PL/I applications that use Assembler, and how to debug and test them. The assumption is that you will be adding your existing application sources to an Eclipse project.

1. Start Eclipse and open the Team Developer perspective which is the default one for Enterprise Developer.

   You can also choose the COBOL or PL/I perspective, depending on the main programming language.

2. Configure Eclipse for Assembler development.

   The default settings in Enterprise Developer are settings aimed at Mainframe Subsystem Application development. You can check and fine-tune settings for the editor and for setting Compiler directives from Window > Preferences > Micro Focus.

3. Create a Mainframe Subsystem Application project for COBOL or PL/I.
4. Add your source files - see how for COBOL or for PL/I projects.
5. Set Compiler directives on the source files - for COBOL and for PL/I.
6. Specify project and build configuration properties - for COBOL and for PL/I projects.

   For example, you can specify a CICS and SQL preprocessor settings, Assembler, and specify a character set and a COBOL dialect. See also:

   • Specify location for the output files
   • Settings for Assembler copybooks and macros that use EXEC CICS
   • Linking considerations
7. Edit your source files - see some tips for COBOL, PL/I, and Assembler files.
8. Build your COBOL or PL/I application.
9. Configure the project:
10. Debug applications
11. Configure Programs' Memory Requirements
12. Use the GTF
