n is either 1 or 0. The default value is 0.
When SaveMac is enabled (n = 1), the source code (.MAC and .INT) for cached query routines created through Dynamic SQL is saved.
Changing This Parameter
On the SQL page of the Management Portal (System Administration > Configuration > SQL and Object Settings > SQL), select Retain cached query source to enable SaveMac.
You can also change SaveMac with the Config.SQL 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).
