Read one trace of data.

Description from stuff.f:

c----------------------------------------------------------------------
      subroutine sff_RTrace(lu, tanf, dt, 
     &                   wid2line, nsamp, fdata, idata, code, last, ierr)
c
c Read one data block starting with DAST line.
c The File will be closed after reading the last trace.
c 
c input
c   lu              logical file unit
c   nsamp           array dimension of idata and fdata
c ouput:
c   ierr            error status (ok: ierr=0)
c   code            code indicating optional blocks
c   wid2line        valid WID2 line
c   tanf            time of first sample from midnight
c   dt              sampling interval in seconds
c   nsamp           number of samples
c   fdata           data array
c   last            is true if read trace is the last one in this file
c
c workspace:
c   idata           data will be first read to idata and then converted
c                   to fdata using sff_i2f (both array may be in same memory
c                   space - see comments on sff_f2i)
c
      integer lu, nsamp, idata(nsamp)
      real fdata(nsamp), dt, tanf
      logical last
      character wid2line*132, code*(*)
