            LAS\GET [N [version]|FIRST|LAST|NEXT|PREVIOUS|ZERO]

        GET  copies  R into T, and loads the Observation number N in R. The cur-
        rent index initialized by FIND is first explored, then, if  needed,  the
        whole  input  file. If N is absent, the previous (last read) Observation
        is recovered.

        Instead of an observation number, several keywords can also be used:
          - FIRST:    the first Observation of the current index is loaded,
          - LAST:     the last Observation of the current index is loaded,
          - NEXT:     the next Observation in the current index is loaded,
          - PREVIOUS: the previous Observation in the current index is loaded,
          - ZERO:     the internal Observation counter is reset to  0,  so  that
                      next  GET  NEXT  will  get  the first observation. In this
                      unique case, R and T are not modified.
