Hi George, Thanks for the info about the new [gNL] and [gNU] code in DBT 10.6. It's interesting, but I can't thik of a good reason why you would want to actually lock the code so that line spacing couldn't be changed. It seems like an unnecessary precaution to me. Was there an prolific problem of inadvertent changes in line spacing or something? Just curious as to why such a locking code was introduced. Jean
