i think we need a little more context here. mod has recently
(post 5.9.2) been changed; mod was renamed to polymod
and nummod was renamed to mod. what version are you
running? also, the global variable modulus is nil by default,
which probably explains the error message ("NIL is not of
type NUMBER") i see when i launch maxima (5.9.1 or 5.9.2)
and enter mod(1). however after assigning modulus a value,
mod(1) is OK. so maybe you can be a little more explicit
about the sequence of operations here. is it only mod(1)
which is problematic? is mod(2) OK or not?
it would also probably help to report bugs to the sourceforge
bug tracker in addition to posting them to the mailing list.
all the best,
robert dodier
