A term expression has one of the following forms, where T1 and T2 denote term expressions, X denotes a variable, I denotes an integer, and S denotes the current store.

min(X)
evaluates to the minimum of D(X,S)
max(X)
evaluates to the maximum of D(X,S)
card(X)
evaluates to the size of D(X,S)
X
evaluates to the integer value of X. The indexical will suspend until X is assigned.
I
an integer
inf
minus infinity
sup
plus infinity
-T1
evaluates to S(T1) negated
T1+T2
evaluates to the sum of S(T1) and S(T2)
T1-T2
evaluates to the difference of S(T1) and S(T2)
T1*T2
evaluates to the product of S(T1) and S(T2), where S(T2) must not be negative
T1/>T2
evaluates to the quotient of S(T1) and S(T2), rounded up, where S(T2) must be positive
T1/<T2
evaluates to the quotient of S(T1) and S(T2), rounded down, where S(T2) must be positive
T1 mod T2
evaluates to the modulo of S(T1) and S(T2)
T1 rem T2
evaluates to the remainder of S(T1) and S(T2)
