C   --*** SQZLGV *** (TPLOT) Compress time-dependent values
C   --   Written by Amy Gilkey - revised 11/06/87
C   --
C   --SQZLGV compresses time-dependent curve values so that only the
C   --values for whole time steps are in the curve.
C   --
C   --Parameters:
C   --   NPTIMS - IN - the number of selected time steps
C   --   IPTIMS - IN - the selected time steps
C   --   WHOTIM - IN - true iff whole (versus history) time step
C   --   VALIN - IN - the input data
C   --   NPTOUT - OUT - the number of selected whole time steps
C   --   VALOUT - OUT - the output (compressed) data
