    FIND performs a search in the input file to build a new index, according
    to  selection criteria defined by the SET command. These criteria may be
    temporarily modified by the following options:
    /ALL                  all versions of each scan are searched for
                          (if not present: only the last version)
    /LINE name            search by line name
    /FREQUENCY f1 f2      search by signal or image frequency value or range
    /NUMBER n1 n2         search for the specified range of observation numbers
    /ENTRY  n1 n2         search for the specified range of entry numbers
    /SCAN s1 s2           search for the specified range of scan numbers
    /SUBSCAN s1 s2        search for the specified range of subscan numbers
    /OBSERVED d1 d2       search for these dates (JJ-MMM-YYYY)
    /OFFSET a1 a2 [unit]  search for this position (within SET MATCH tolerance)
    /QUALITY q            search for the data of quality better than Q
    /RANGE w e s n [unit] search for the specified range of offsets (plus SET MA
    /SOURCE name          search by source name
    /TELESCOPE name       search for the telescope used
    /SECTION name         search for observations which have this section define
    /MASK File            search for observations in the mask

    FIND does not return an error if the index is empty,  but  the  variable
    FOUND  is set to 0. FOUND is always set to the number of observations in
    the index.
