No. You are still accesing the data line by line (i.e. from the start each
time), rather than splitting it up by using "repeat for each" - which goes
through the data just once start to finish. Even though your script is
altering lines in a variable, it is still going to be much faster (if there
is a lot of data) to *rebuild* that variable in another (e.g. tFinalData,
below):
put empty into tFinalData
repeat for each line l in tData
--do something to l, e.g. put "modified" after it
put l && "modified" & cr after tFinalData
end repeat
delete last char of tFinalData --always remove trailing cr
