ass(..., PrintLevel => ...)

ass(..., PrintLevel => ...)

The PrintLevel should be one of the following.

0 -- (default) Returns the list of associated primes.

1 -- Returns strategy number, associated primes as they are found, and full list at the end.

2 -- Returns the results of PrintLevel=>1 and signals presence in loop. With Strategy => 1, the codimension of the associated primes is the loop number.
