The Application painter has a menu item on the Edit menu named Default Global Variables that allows you to specify user defined types for SQLCA, SQLDA, SQLSA, ERROR and MESSAGE.

The Default Global Variable Types dialog opens when the new menu item is selected. The variable types must be descendants of the default type. For example, to set the default global variable for SQLCA, you must first create a standard class user object of type transaction and save it in the User Object painter. Then you enter the name of that user object in the edit control for SQLCA. Use the OK button to save the entered values. If you want to reset the values to the defaults, click the Reset button. Remember that if you use the Reset button you must also use the OK button to save the changes.
