.PLOT FILE: CNT001
[Enter name of the existing contour storage metafile.]

.CLEAR THE SCREEN FIRST? (Y/N): Y

.Enter viewport size (100-480):

.DO YOU WANT TO WINDOW? (Y/N): N
[This question only occurs for some devices. Windowing allows you to plot only a portion of the plot metafile. If the answer is "Y" then the following two questions appear. The window is calculated assuming a normalized 1.0 by 1.0 plot.]

.ENTER X & Y CO-ORD. OF BOTTOM LEFT CORNER (0.0 - 1.0): .0 .5

.ENTER X & Y CO-ORD. OF TOP RIGHT CORNER (0.0 - 1.0): .8 .9

.CENTER THE PLOT? (Y/N): Y
[A "Y" answer centers the output on the device.]

Lists current display scale.

.ENTER NEW DISPLAY SCALE OR <CR>: 450
[You can alter the plot size by entering a different value.]

.PRINT TEXT? (Y/N/M): Y
[Can omit text if desired. An answer of "M" will mirror output around a X axis so as to flip the top and bottom of the plot.]

.PLOT AGAIN (P), HARDCOPY (H), DO NOT CLEAR(D) (P/H/D):

NOTES

  1. The different output devices may vary somewhat in the questions which appear, depending on the capabilities of the device.
