Thanks very much Bob! Yes, it's always nice to do everything within
JmolScript itself -- I very much appreciate seeing how to achieve this same
functionality that way (very educational)! Two questions: 1) Would you mind
if I added your example code to the wiki along with the one that I added
yesterday so that others can find two alternate means to the same end?! and
2) there is one line in your code that contains a construct I'm not familiar
with. Would you, or someone else with more programming experience than
myself (read: almost anyone!), explain to me what this is doing:
titleLines[i] = (titleLines[i])[11][0].trim() ?
It looks to me like you're taking everything "extra" off the beginning and
ends of each line in the titleLines array, but it's the [11][0] syntax that
has me stumped....If they are positions in the line array, then is this a
selection from the beginning of the actual title text to the end of that
line?
