You can set different project and file properties to control the way you build your COBOL projects.
Overview of COBOL Project Properties
You can specify default properties that apply to the COBOL projects in all or selected build configurations, and to individual files in the projects. You can also configure the directives scan feature which automatically determines and sets Compiler directives on the COBOL source files in the IDE.
Options for Setting Directives when Scanning Files
The IDE is configured to automatically perform a directives scan and set Compiler directives on any COBOL files you add to your projects. You can also start a directives scan manually using the Reset source directives context menu command in Solution Explorer. Each file is examined to determine the directives required and the directives are set on the file accordingly. However, if the directive is already set on the project, it is not set on the file.
Global Options
The options you set in the IDE, in Tools > Options, apply to all COBOL projects.
Project Properties
The COBOL project properties comprise some properties that apply to the project generally, regardless of the type of build, and some properties that apply to specific build configurations of the project, such as a debug build or release build.
To specify file properties
Files inherit the properties set on project level. You can, however, specify individual file properties and they override the ones set on project level.
To reset the directives on COBOL files
This triggers a directives scann of the COBOL files in your project and sets Compiler directives on them as specified in Tools > Options > Projects > COBOL Project Settings.
