Gentlemen - I want to thank each and every one of you who responded to my query. I have been busy with "life issues", chief among which has been the sudden need of a close friend's help due to a sudden medical problem in which removal of most of his intestines has been "the solution".

While on the subject of digestion,in a manner of speaking, there is certainly a lot here to go through! I want to give as much effort in comprehending your posts as it took to write them. Just a cursory once-over certainly will not do.

I will no doubt have more questions once I've gone through all your posts. Just wanted to let you know how much I appreciate your contributions and also explain my silence over the past days.
