through the LOW NORTH computation.
RPC
Name: Random Point Contour
Purpose: This allows the entry of elevation points into
the random pointfile for topography work during
plotting.
Keystrokes:
Entry Conditions: None
Operation: When executed the CO-OP 41 will prompt for
contour point pairs that you wish to interpolate between
when you are working with topography.
[1ST POINT?
[2ND POINT?
After you key in both of these values the CO-OP 41 will
prompt for the second pair of points. Continue with this
until you have stored all your elevation lines.
To close this file respond with zero (0) for each of the two
final point prompts. To actually plot the contour tick
marks see the CONTOUR function.
Note This function destroys the random pointfile to
store the contour information in it. Any data in
#9 the random point file will be lost.
