From the project properties in Visual COBOL, you can set a variety of Compiler directives that control the way your applications build. To specify directives that do not have a property equivalent, you need to type them in the Additional directives field on the COBOL tab in the project's properties.
Micro Focus recommends that you always use the project's properties to set Compiler directives for those that have property equivalents and avoid using the Additional directives field to specify them.
If a directive that has a property equivalent is specified in Additional directives instead, and you want to override this at file level, for example by using Determine Directives, the directive specified in the project's Additional directives might override the file's properties. This can result in unexpected build issues when building your applications.
To help resolve such issues, Visual COBOL performs a check on Additional directives when opening COBOL projects and, wherever applicable, shows an Update COBOL Project Properties dialog box that suggests converting any directives specified in this field into the equivalent project properties.
This dialog box might start to appear if, for example, you upgrade Visual COBOL to a newer version that has more project property equivalents for Compiler directives. You need to review the suggested changes carefully before accepting them. This is how this feature works:
If there are any additional directives that have project property equivalents, this causes the Update COBOL Project Properties dialog box to be displayed, which lists the additional directives and the suggestions for project properties to replace them with.
Visual COBOL removes the specified directives from the Additional directives, and enables them as the relevant project properties.
For example, if Additional directives included the LIST() directive, the conversion removes it and enables the Generate listing file project's property.
If you do not want the IDE to perform this check, click Tools > Options > Micro Focus > General and uncheck Check Additional Directives for project properties.
