use repeat for each line L ... and collect the modified lines in a
separate variable, replace the original variable after the loop
repeat fer each line L in tData
put ... & CR after temp
end repeat
put temp into tData
should be very quick.

btw - not needed in this case, but you could use split/combine in it's
"single separator" form
split tData by CR
repeat with i = 1 to the number of lines in the keys of tData
put .... into tData[i]
end repeat
combine tData by CR

Problem:
I have a long list of several thousand lines.
Each line contains two comma-separated numbers.
I want to divide the first item of each line by one divisor, and divide the
second item of each line by a different divisor.
The list order must stay the same.
Example:
Using 2 and 5 as divisors...
10,10
12,15
8,12
would become
5,2
6,3
4,2.4
Options:
Using "repeat with n=1 to num of lines" takes far too long.
Using "repeat for each line L" either attempts to modify read-only data, or
is only 25% faster using a dumping variable.
Using split/combine will mess up the ordering (numeric array keys are not
sorted numerically with combine).
Any other ideas?
