If everyone in the world uses i and j as row/column indexes into arrays, aren't they self-documenting? One reason is that in FORTRAN, identifiers that began with I through... N? were automatically integers. Thus, I and J were easy. There may be a good reason for that, I've heard that it came from quaternions but that may be false. John
