Diagram
After users click ??? above an object inserted in a network, they can type an operand.
The users can click in the box, and select a symbol on the drop-down list. If a symbol whose
data type is ARRAY is declared, the elements in the array will be on the drop-down list. Ary[0], Ary[1],
and Ary[2] in the figure below are elements.
The users can type a device name or a symbol in the box. If they type a symbol which is not
declared, the Add Symbol window will appear after they press Enter on the keyboard. (Please refer
to section 2.3.1 for more information about declaring a symbol.)
After users click a network and press Enter on the keyboard, they can edit a box. The users can edit
the next box in the network after they press Enter on the keyboard. Besides, the next network will be
selected after the users press Tab on the keyboard. The users can edit a box with the keyboard. If
the users have declared symbols, they can press Page Down on the keyboard when they edit a box.
The symbols on the drop-down list are symbols which can be assigned to the operands. The users
can select a symbol by the mouse or the up/down key on the keyboard. After the editing is complete,
the users can press Enter on the keyboard to jump to the next box. If the users want to end the
editing, they can press Esc on the keyboard.
