C   INPUT NOTES:
C-----------------------------------------------------------------------
C   KMAX   = Number of points in eta (marching direction)
C   ETAMX  = 0  March to the end of the end of the underlying grid
C          > 0  Distance to march out from initial curve
C   DETA   = First grid point spacing in marching direction from initial
C            curve (or 0 for no spacing control, or -factor to use
C            reference collar grid spacing times constant factor)
C   DFAR   = Last grid point spacing in marching direction from initial
C            curve (or 0 for no spacing control)
C   MARCH  = +J  March collar in the +J direction
C            -J  March collar in the -J direction
C            +K  March collar in the +K direction
C            -K  March collar in the -K direction
