USER FUNCTION DEFINITION screen.
• As a condition for an automatic analysis function on the DISPLAY: ANALYSIS
SETUP screen.
• For direct keyboard calculations.

The following are restrictions for using read out functions:
• GRAPHICS must be selected in the DISPLAY MODE field on the DISPLAY:
DISPLAY SETUP screen when you use the read out function. If not, invalid data
is returned. (@MI is an exception. @MI can be used in GRAPHICS or LIST
mode.)
• If the marker, cursor, or line that are referred to by the read out function are not
displayed, the read out function uses the position at which it was most recently
displayed. If the marker, cursor, and line have not been displayed, the read out
function returns invalid data.
• You cannot assign a data variable that includes a read out function to an axis of
graphics plot.
