LIST /TOC

            LAS\LIST [IN|OUT] /TOC [Attr1 Attr2 ... AttrN] [/VARIABLE VarName]

        LIST /TOC displays the Table Of Contents of the current index, or of the
        input  (LIST  IN)  or output file (LIST OUT). A summary of the different
        values of each attribute is made, plus a final summary of all the combi-
        nations (setups). The attributes can be:
            - SOURCE
            - LINE
            - TELESCOPE
            - OFF1
            - OFF2
            - ENTRY
            - NUMBER
            - BLOCK
            - VERSION
            - KIND
            - QUALITY
            - OBSERVED
            - SCAN
            - SUBSCAN
        The  following  attributes are more relevant in the context of continuum
        drifts:
            - DRIFT (compatible continuum drift position angles i.e. same  angle
                    modulo 180 degrees within tolerance)
            - DIRECTION (identical continuum drift position angles i.e. same an-
                    gle modulo 360 degrees within tolerance)
            - FESB (based on telescope name but only same frontend+sideband)
            - FRONTEND (based on telescope name but only same frontend)

        By default, SOURCE, LINE and TELESCOPE are used.

        The table of contents is also saved in  a  SIC,  user-defined  structure
        thanks  to  the  option  /VARIABLE (default is TOC%). The content of the
        structure is updated after each call to the command LIST /TOC. One  must
        take  care  that subsequent calls to FIND can lead to values in TOC% in-
        consistant with the current index.
