   EVOL1_V=FREQPERI EVOL2_A MOT1;

   Description :
   -------------

   This procedure transforms an acceleration response spectrum
   EVOL2_A (including N curves) in frequency or period into a
   velocity response spectrum (including N curves) in frequency
   or period, depending on whether MOT1 equals 'FREQ'(uency) or
  'PERI'(od).
