1 more speed question

[jbv]

for year we've been told that
    repeat for each line j in myVar
runs significantly faster than
    repeat for i=1 to number of lines in myVar

that's true, but if you use the following
    repeat with i=1 to number of lines in myVar
        get line i of myVar

and then do all your processing in the "it" variable
(and then "put it in line i of myVar" at the end of the
repeat loop if necessary), in that case the "repeat with i..."
statement seems to run as fast as "repeat for each line..."

does that mean that only the fact that each successive line
is in a variable (and hence has its content easier to access
than in a huge variable with dozens or hundreds of lines)
matters, and that it has nothing to do with the repeat
structure per se ?

Thanks,
