.SH DESCRIPTION
\fVlocate\fR is used to get the coordinates of one or more
points selected with the mouse in a graphics window. The coordinates
are given using the current graphics scale.
If n>0, n points are selected and their coordinates are returned in
the matrix \fVx\fR.
If n<=0, points are selected until the user clicks with the left button
of the mouse which stands for stop. The last point (clicked with the left
button) is not returned.
x=locate() is the same as \fVx=locate(-1)\fR.
.LP
If \fVflag=1\fR a cross is drawn at the points where the mouse is clicked.
