SONSetRealChan

  SONSETREALCHAN creates real wave channel     

  RET=SONSETREALCHAN(FH, CHAN, SPHYCH, DVD, BUFSIZE,...
                                COMMENT, CHANTITLE, SCALE, OFFSET, UNITS)

              FH = SON file handle
              CHAN = the channel number for the new channel
              SPHYCH = the physical channel number
              DVD = the number of clock ticks per sample
              BUFSIZE = the size of the internal buffer (up to 32768 bytes)
              COMMENT = channel comment string
              CHANTITLE = channel title string
              SCALE = scale factor
              OFFSET = offset
              UNITS = channel units string

  Returns zero or a negative error
