The optional AT server phrase in the CALL or EXEC command determines where the calling procedure should look for the called procedure.

In most cases, you do not have to supply this phrase. WebFOCUS Maintain does it for you. When you define the deployment scenario for your project, you decide on which WebFOCUS Servers each procedure will run. Then, when you deploy your project, WebFOCUS Maintain places the appropriate AT server phrase in your CALL and EXEC statements, so that the application will work properly.

This information is useful for two reasons:

• If you edit the procedures that WebFOCUS Maintain deployed to the WebFOCUS Server, you will see the AT server phrases in these procedures.
• If you want to CALL or EXEC a procedure in your application that is not part of your project, you must manually include the AT server phrase in your CALL or EXEC statement, so that the calling procedure knows where to find this procedure.
