PlanAhead - Is the Tcl "clear" command supported?


Is the Tcl command "clear" supported in the PlanAhead tool? 

On a Windows OS, when I enter "clear" in the Tcl console I receive the following error: 

ERROR: GetConsoleScreenBufferInfo(): The handle is invalid."

On a Linux OS, There is a similar problem with the clear shell command. 

However, there is no message, just control characters printed in the console log.


PlanAhead tool 13.x does not have a Tcl command to clear the history from the console.

The PlanAhead GUI implements this feature (Clear all output in the Tcl console) with the "x" button in the menu at the left of the Tcl console.
