    Topic complex Table functions
    Function lastrec()
    Short Number of the last record according to the actual access
    Syntax LASTREC(db : INTEGER) : INTEGER
    Parameter db : table handle from OpenDB
    Return physical record number of the last record
    See also:
    firstrec() nextrec() prevrec() firstmark() nextmark()
    Description Depending on how the access with ACCESS was set for the table, FIRSTREC returns different results:

    Marking (-2): last record in marking list
    Number (-1) : filesize(db)
    Index (0..15) : record with the biggest index information

    Example: Complete discending pass through a table via an index

    db:=OpenDB(...);
    access(db,1); // Set access on index
    x:=lastrec(db);
    WHILE x DO
    readrec(db,x);
    ... here the record is available
    x:=prevrec(db)
    END;
