    Parameters:

    TAG1	(I1)	Specify segment number SEG1 in th set of segments
    SEG1	(I2)	having tag TAG1.  If TAG1 is blank or zero, then SEG1 is the segment number.

    TAG2	(I3)	Same as above.
    SEG2	(I4)

Notes:

- Up to five segments may be specified on 2-1/2 CP cards. Coupling is computed between all pairs of these segments. When more than two segments are specified, the CP cards must be grouped together. A new group of CP cards replaces the old group.

- CP does not cause the program to proceed with the calculation but only sets the segment numbers. The specified segments must then be excited (EX card) one at a time in the specified order and the currents computed (XQ, RP, NE, or NH card). The excitation must use the applied-filed voltage-source model. When all of the specified segments have been excited in the proper order, the couplings will be computed and printed. After the coupling calculation the set of CP cards is cancelled.
