Concept

Purpose

The DQL Procedural commands are used to organize and control the flow of actions in a procedure.

Usage

Procedural commands can be used in both Processing procedures and Control procedures.

Example

case ( spellweekday ( weekday( current date) )

value "MONDAY" :

run procedure "LAST WEEK SUMMARY" .

value "FRIDAY" :

run procedure "PRINT RESERVATIONS" .

others :

call menu "MAIN MENU" .

end

This script tells DataEase: (1) If the current date is a Monday, run the LAST WEEK SUMMARY procedure, (2) if the current date is a Friday, run the PRINT RESERVATIONS procedure, and (3) if the current date is any other day of the week, display the MAIN MENU.
