SURVO MM supports graphical operations PLOT on PostScript printers (PS) and GPLOT in the screen graphics. A PostScript printer is ideal for producing plots of high quality and for making multipage documents with graphical illustrations (see option - picture in PRINT?). PostScript files made by Survo can also be printed by means of various Windows programs (like GSview and Adobe Acrobat) on any Windows printer. Plots on the screen are useful when planning graphical illustrations and in interactive graphics. Since the screen plots can be saved on the disk as enhanced metafiles, also sequences of pictures and overlays of them may be created. The PLOT operation and the GPLOT operation are almost identical in most applications. When a plotting scheme has to be transferred from the screen to printers or plotters or vice versa, it is usually question of changing PLOT to GPLOT and adjusting some dimension parameters (like SIZE) only. Often such adjustments can be avoided by using specification MODE=PS in GPLOT plotting schemes.
