Description

If DisplayModeDisplayModeDisplayModeDisplayModedisplayMode is set to VarRef('on'), which is the default, within the selected procedure the PC is always displayed left to the currently executed operator. In addition the program text is scrolled---if necessary---so that the current operator is visible.

If the mode is 'off'"off""off""off""off" the PC is not visible during program execution and the program text will not be scrolled automatically. When the program stops the PC becomes visible again and the listing is scrolled to the current PC position.
