digraphs are not synonymous with mnemonics. Perhaps you can point out where the RFC mentions this sort of use - reading through it, I don't see it. If there's no relation, using an RFC is a pointless appeal to authority. short - I was pointing out that your description of the background for the report was inaccurate.

There's a small table in screen now, and you want to replace it by a large table. Since you haven't presented any information regarding the performance I have to conclude that you didn't consider it. bye -- Thomas E. Dickey http://invisible-island.net ftp://invisible-island.net
