Function
Expands and simplifies an algebraic expression, modulo
the current modulus.
AR!TH] MODULO
An expression.
The expanded and simplified expression modulo the
current modulus.
Exact mode must be set (flag -105 clear).
Numeric mode must not be set (flag -03 clear).
Expand the following expression and give the result
modulo 3 (the default modulo setting):
(.T+3)(.r + 4)
E X P A N D M O D ! ( X + 3 ) * ( X + 4 ) )
