Changes display in current window to the previous display in stack. If there is no graphic in the stack or the current pointer is at the beginning of the display stack, the command does not change the display. The display stack has a maximum of 100 displays. Restarting the WebAccess Client or ViewDAQ clears the alarm stack. This command will interact with the keymacros <HISFORW> and <HISBACK> and the similar tool bar keymacros.
Examples: # tcl or VB
HISBACK
// JScript
HISBACK();
