Hi JB,
Repeat for each has proven to be surprisingly fast, before. So, I
wouldn't be surprised if it beats the offset function, although I do
wonder why the offset function would be that slow.
Best,

Hi list,
Please excuse the remark, but I'd like to share something I just noticed
and that surprised me a bit...
I have a file loaded into a variable, which is about 8 Mb and consists
in
about 4 lines of 3 items each (itemdel is tab).
I need to know which line contains a certain value as
I would be curious to know how the filter command works with your particular
data set. One of the speed difference factors I find is the exact
configuration of the data.
The filter command works fastest if the 'target' string in the first part of
a the line, and repeat for each seems to be much

actually I guess that lineoffset and filter, once compiled, use rather
complex routines, while repeat for each line remains much closer to raw
and efficient C code...
Yes, that's my understanding, at least for the filter command which
drops into a rather complex regex subsystem, so
Surprisingly, this takes only 106 ms !!!
If anyone asked me beforehand, I would have sweared that a built-in Rev
function would run faster than a bunch of transcript lines of code...

Richard,
I don't understand why lineoffset is slower, however, and have submitted
a request to have it reviewed for potential optimization:

I'm wondering if lineoffset could get slower when the wholematches are set to
false...
I might

Wil, if you're seeing this, I just want to apologize for mangling your last
name - I just realized it should have been Dijkstra. (Hey, at least I got
the j in there! :-)
