SENTER Segment Entry for Frequency Limit Lines
n POINT specifies a limit value for the coordinate point, and no other frequency points, so
that a POINT segment specifies a limit value for a single frequency. For an upper limit-line,
a POINT segment is indicated by a line drawn from the coordinate point, vertically off the
top of screen. For a lower limit-line, a POINT segment is indicated by a line drawn from the
coordinate point, vertically off the bottom of screen. The POINT segment type should be
used as the last segment in the limit-line table. However, if the last segment in the table is
not specified as the POINT segment type, an implicit point is automatically used. If a visible
POINT segment at the right-hand edge of the display is not desired, add an explicit last point
segment to the limit-line table that is higher in frequency than the stop frequency.
Segments are sorted as they are entered according to starting frequency. A maximum of 20
segments can be defined using SENTER. When the type is omitted, the last type given (or
SLOPE if no previous type has been given) is used.
