Sorry, Richard, I probably don't completely understand your question.
I'd guess you were once a HC user, but maybe not. SS stands for
searchscript. It was a script that shipped with hyperCard, in the home
stack. It was invoked by typing SS into the msg box. It searched for a
string in every script in the top stack.
You asked about "each of these scripts." That's the part of your
question I didn't understand.
FWIW, I was comparing the speed of Rev's Find stack, searching for a
string in any script in the top stack versus hyperCard's SearchScript
doing the same job in a similar stack, in classic mode. But you probably
understood that part.
Beyond that, I once wrote a test script comparing the milliseconds at
beginning and end of script, the "find" command in a repeat loop, to
find every instance of a string in any field of a rather large stack. I
compared the elapsed time to the time Rev's "Find" stack took to do the
same job, in the same stack, searching for field text only. I reported
the whole thing on the list 2 or 3 months ago.
As I recall, the "find" command was 59 times faster than the
field-text-only find, using Rev's "Find" stack. It was easy to calculate
because the script took less than two seconds, whereas the "Find" stack
needed more than a minute to do the same job.
Maybe that's what you were asking about. Not sure.
It seems you understood my question well in spite of my vaguery. :)
Rev is generally faster than HC with the exception of certain uses of
"find" (thanks to Atkinson's patented 'hint bits'), so I'd be curious to
read an analysis of why the two search solutions are so very different.
I haven't used SS before, and am not even sure if I still have HC
installed on this machine. I don't use the Rev IDE either, but at least
I do have it around somewhere and could dig out the search window.
With SS, what does the result give you? Does it produce a list of found
objects, or take you to them sequentially?
I'm pretty confident Rev can deliver a search solution that performs
roughly on par with HC overall, esp. if we're talking about just
searching scripts rather than fields, as I believe "hint bits" only
apply to field objects.
Maybe I can squeeze some time to sit down with those two scripts and
figure out where the time is being spent....
