Clearing the Display

￿IP blanks the display line, trace B, and trace C by executing DL OFF, BLANK TRB , and BLANK TRC automatically.

￿CLRDSP erases all user-created graphics from the display and memory, except the contents of the title line. If you have stored graphics you wish to recall for future display, use the DELETE command to erase items individually.

￿ANNOT OFF blanks all annotation except the display status box and the data line.
