CREATES A SYSTEM OBJECT MAIN_MENU AND ALLOCATES IT NUMBER N AS REFERENCE

  • Type: Command
  • Parameter: 1
  • Group: System Objects Creation

ACTION

The command MAIN_MENU N creates a system object MAIN_MENU, and allocates it a number N. The number N will be used to designate the MAIN_MENU.

The created MAIN_MENU can then be used through the appropriated commands.

A MAIN_MENU is used to design a menu system with its accompanying drop-down menus on a FORM. There is only one MAIN_MENU per FORM.

A MAIN_MENU cannot generate an event. The events are attached to the SUB_MENU.

Remark: by default, the MAIN_MENU is created on the FORM number 0, but another FORM can be used. For that, create a FORM by FORM N, and send it all the commands by COMMAND_TARGET_IS N before creating the MAIN_MENU.

SYNTAX: MAIN_MENU N

  • N = system object number (integer or real). Must be greater than 0 and less than or equal to the allowed maximum number of system objects.

USE

  • A MAIN_MENU is used to design a menu system with its accompanying drop-down menus (with command SUB_MENU) on a FORM.

ERROR

  • If number N is not a correct expression.
  • If number N exceeds the allowed maximum number of system objects.
  • If number N is less than or equal to 0.
  • If number N is already used for a system object number.
