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
        - SCAN
        - SUBSCAN
    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.
