1 EVALUATE 

        EVALUATE expression [/qualifier]

    Computes and displays the value of the specified expression in both
    hexadecimal and decimal.  If the expression is equal to the value of
    a symbol, that symbol is displayed.  A finite number of such symbols
    is displayed by default.  If no symbol with this value is known, the
    next lower valued symbol is displayed with an appropriate offset if
    the offset is small enough for the selected symbol to be considered
    useful.

    Alternate evaluations of the expression are available with the use of
    the qualifiers defined for this command.
