C  PURPOSE: INTEGRATES POWER SERIES OF THE FORM:
C
C           X**IPC * EXP( UC * X ) * ( C(1) + X * C(2) + .... )
C                                     <------ NC TERMS ------>
C
C           TO GIVE AN ANSWER OF THE FORM:
C
C           -X**IPD * EXP( UD * X ) * ( D(1) + X * D(2) + .... )
C                                      <------ ND TERMS ------>
C
C           NOTE SIGN OF OUTPUT.
C
C  CALLING PROGRAM: ADAS308.
C
C  INPUT : (I*4)  MXTERM  = MAXIMUM NUMBER OF TERMS.
C  INPUT : (I*4)  NC      = NUMBER OF TERMS IN POWER SERIES.
C  INPUT : (I*4)  IPC     = POWER OF LEADING TERM.
C  INPUT : (R*8)  UC      = POWER OF EXPONENT.
C  INPUT : (R*8)  C()     = POWER SERIES COEFFICIENTS.
C
C  OUTPUT: (I*4)  ND      = NUMBER OF TERMS IN POWER SERIES.
C  OUTPUT: (I*4)  IPD     = POWER OF LEADING TERM.
C  OUTPUT: (R*8)  UD      = POWER OF EXPONENT.
C  OUTPUT: (R*8)  D()     = POWER SERIES COEFFICIENTS.
