Control Procedure

Type

Concept

Purpose

A Control procedure is a procedure that lets you link other procedures together with or without conditional processing actions specified by Procedural commands.

A Control procedure can link any number of procedures together and can automatically initiate several actions, including run procedure, backup db (database), install application, etc.

Usage

A Control procedure is used primarily to link Processing procedures together. It can include any combination of Control commands, Processing commands, and Procedural commands.

For a full explanation of any of the DQL commands, see the individual command entry in this lexicon.

Example

if current user name = "PAUL" then

call menu "RECREATIONAL ADMIN" .

run procedure "MAILING LIST" .

else

call menu "MAIN MENU" .

end

This Control procedure tells DataEase: If the current user is Paul, (1) Display the RECREATIONAL ADMIN menu, (2) run the procedure that generates an up-to-date mailing list, and (3) if the current user is not Paul, display the main menu.
