TheSET ECHOstatement specifies a location for thePLOTTER ISecho indicator. If thePLOTTER ISdevice is a display, the echo is a cross-hair. If thePLOTTER ISdevice is a plotter, the echo is the pen or device pointer.
The cross-hair is displayed at the specified location if it is within the device limits. If the specified location is outside the device limits the cross-hair is not displayed. Thus, to turn off the cross-hair, specify a position off screen.
The plotter pen is moved (with the pen up) to the specified location if it is within the clip limits. If the specified location is outside the clip limits the pen is moved to and then along the clip limit.
The location returned by theREAD LOCATORstatement can be used with theSET ECHOstatement to cause the echo to track theGRAPHICS INPUT ISlocation.
