Specifying an ESQL Preprocessor and Compiler Directive Options

Generally, you also set applicable preprocessor compiler directive options when you specify the preprocessor; however, you can use a combination of methods at your preference. The order in which the COBOL compiler calls the preprocessor depends on where you specify it. We provide several alternatives:

In the Visual COBOL IDE
You can specify an ESQL preprocessor and its applicable compiler directive options on the SQL tab of your project properties. Do this when your primary method of compilation is building a program or application from the IDE.
On the Command Line
When compiling from the command line, you can specify your ESQL preprocessor and its directives in the sequence of compiler directives specified as arguments to the cobol command.
In a Directives File
You can specify your ESQL preprocessor and its directives in the cobol.dir system-wide directives file and/or in a user directives file.
Embedded in the Program
You can also specify a preprocessor on the program level by embedding a $SET statement into the program itself. Use this method only when the program requires a preprocessor different from other programs in an application.
