What were your results? On this machine (Mac PB 1.5mhz) I got:
10000 lines in a field with approx. 1000 randomly placed empty lines
put fld text into variable, repeat for each, place new list into fld
-- 78 millisecs
put fld text into variable, filter variable, put back into field --
72 millisecs
simply filter field -- 70 millisecs
So not a huge difference between any of them.
Best,
Mark

... you could do it like
put fld 'emailList' into tEmailList
put empty into tNewEmail
repeat for each line tEmail in tEmailList
if line tEmail is not empty then
put tEmail & CR after tNewEmailList
end if
end repeat
put tNewEmailList into fld 'emailList'
but easier would be
put fld 'emailList' into tEmailList
filter tEmailList without empty
put tEmailList into fld 'emailList'
Easier to script, yes, but note the result from running this script
which compares both methods:
on mouseUp
put 1000 into N
put fld 1 into tData
--
--
-- 1. repeat for each
--
put the millisecs into t
repeat N
--
put empty into R1
repeat for each line tLine in tData
if tLine is not empty then
put tLine &cr after R1
end if
end repeat
delete last char of R1
--
end repeat
put the millisecs - t into t1
--
--
-- 2. filter:
--
put the millisecs into t
repeat N
--
put tData into R2
filter R2 without empty
--
end repeat
put the millisecs - t into t2
--
--
-- Result:
put t1 && t2
end mouseUp
Did I write this wrong?
Seems most times I benchmark "repeat for each" with the well-
optimized "put after" I get results that hold up surprisingly well.
I have another post in the works with some other interesting
benchmarks related to processing lists (things I learned on summer
vacation <g>)...
