n is either 1 or 0. The default value is 0.
When DDLSQLOnlyCompile is enabled (n = 1), any class compilation performed as a result of executing a DDL statement compiles the class with the q (sqlonly) flag. When this parameter is not enabled, the q flag is not used.
Changing This Parameter
You can change DDLSQLOnlyCompile with the Config.SQLOpens in a new tab class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
