tbl[wi][bi] would be indexing the bi'th element of whatever tbl[wi] returns. For Numeric arrays, you need tbl[wi,bi] Now, you'll have another problem as Terry Reedy mentioned: the indices (in Numeric) need to be Python ints, not longs. You could rewrite your test() function as def test(): val = testme() wi = int(val >> 4) bi = int(val & 0xF) print wi print bi print tbl[wi,bi] and that'll work. -- |>|\/|< /--------------------------------------------------------------------------\ |David M.
