[]
    Elements of an array can be identified using subscript expressions.
     Consider the following 3-dimensional array defined in the "C" language.

    Example:

         char *ProcessorType[2][4][2] =
             { { { "Intel 8086",   "Intel 8088"  },
                 { "Intel 80186",  "Intel 80188" },
                 { "Intel 80286",  "unknown" },
                 { "Intel 80386",  "unknown" } },

               { { "NEC V30",      "NEC V20" },
                 { "unknown",      "unknown" },
                 { "unknown",      "unknown" },
                 { "unknown",      "unknown" } } };

    This array can be viewed as two layers of rectangular matrices of 4 rows
    by 2 columns.  The array elements are all pointers to string values.

    By using a subscript expression, specific slices of an array can be
    displayed.  To see only the values of the first layer, the following
    expression can be issued.

    Example:

         processortype[0]

    To see only the first row of the first layer, the following expression
    can be issued.

    Example:

         processortype[0][0]

    To see the second row of the first layer, the following command can be
    issued.

    Example:

         processortype[0][1]

    To see the value of a specific entry in a matrix, all the indices can be
    specified.

    Example:

         processortype[0][0][0]
         processortype[0][0][1]
         processortype[0][1][0]

()
    The function call operators appear to the right of a symbol name and
    identify a function call in an expression.  The parentheses can contain
    arguments.

    Example:

         ClearScreen()
         PosCursor( 10, 20 )
         Line( 15, 1, 30, '-', '+', '-' )

.
    The "." operator indicates field selection in a structure.  In the
    following example, tyme2 is a structure and tm_year is a field in the
    structure.

    Example:

         tyme2.tm_year

->
    The "->" operator indicates field selection when using a pointer to a
    structure.  In the following example, tyme is the pointer and tm_year is
    a field in the structure to which it points.

    Example:

         tyme->tm_year
