Why is it!? Why do our bodies fail us just when
our minds finally figure out now to hit a down the
line backhand? It's a mystery. :-(
Why don't you try this in your journal file:
I = where(ots eq 'o' and nnp ge 0 and agp lt 10., cnt) & Print, cnt
Cheers,
David

well, thanks David . . . I guess I should have said that I knew that there
were ways in this case to get around the problem - but what if there was
information that only the help command could give you that you wanted to show
