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,
Mark

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 40000 lines of 3 items each (itemdel is tab).
I need to know which line contains a certain value as 3rd item.
Fist I used the following :
get lineoffset(tab & "39900",myVar)
which happens to take 200 ms when the found line is near the end.
Then I tried this :
put 0 into x
repeat for each line j in myVar
add 1 to x
if last item of j = "39900" then
put x into tResult
exit repeat
end if
end repeat
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...
I'm using Rev cgi 2.5 on a Linux server.
JB
