A comment on exercise 1.4(d). Mini-Triangle does not have a >= operator. It is, however, possible to derive m >= n as possible: Expression => Expression Operator primary-Expression => Expression Operator Operator primary-Expression => Expression > Operator primaryExpression => Expression >= primaryExpression =>* m >= n. This assumes that no space is needed to separate operators. As as far as I can see, there is no requirement of having spaces between symbols of Mini-Triangle. (There is a comment on spaces in Triangle on p.398.) I gave credit to students who wrote that m >= n is not an expression (because I think they assumed that >= needs to be written with a space between the > and the =), and to students who wrote that m >= n is an expression, provided that they gave a good syntax tree, in which > and = are shown to be separate operators.
