Singular has the option command which internally set/clears bits in a 64bit vector.
(Not all of the bits have names).
test as a command allows to access these bits by there number instead of their name - undocumented, as these changes all the time and should not be used.
(And it is defined in Singular/table.h: "test" -> TEST_CMD->jjTEST
and jjTEST (which gets called) is in Singular/iparith.cc)
