The program draws locus curves of any complex function entered in UPN notation. The drawings can be executed in four different formats: Window (content of the largest window that can be displayed), STAD (640 x 400, for post-processing with drawing programs), DIN A5 landscape and DIN A4. One pixel corresponds to 1/180 inch square (24-needle). Functions are always drawn in dependence of a variable (x); but four constants can be declared, so that it is also possible to draw function groups.
