SU[rface] <variable> <direction> <value>.... generates a contour surface for a given value of a stored variable. The 'direction', may be 'X','Y' or 'Z', and specifies the planes over which the surface contours will be generated. Usually two out of three will need to be specified, to generate a cross-hatched surface,
eg. SURF P1 X 10.0
SURF P1 Y 10.0
will generate a contour surface for P1=10.0 in the X-Y plane.

[Surface No.] is the sequence number of the SURFACE element in the stack. Typing in any valid number (the total number of SURFACE element) will pop up the corresponding SURFACE element and make it current. Only the attributes of the current SURFACE element can be modified.

SU[rface] OF[f] <element number>....switches off the specified surface element, which will not appear in subsequent plots until it has been switched on again.
