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.
You can also choose the COBOL or PL/I perspective, depending on the main programming language.
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.
For example, you can specify a CICS and SQL preprocessor settings, Assembler, and specify a character set and a COBOL dialect. See also:
Further, to get familiar with the process of developing CICS applications in Enterprise Developer, Micro Focus recommends that you go through the following tutorial:
