Repeat for each line of a variable or field?

I've done a little bit of speed testing showing extremely slight differences, but wonder if anyone who understands the "engine" can advise on this:
Is there a difference between these two approaches?
(1) put fld 1 into txt; repeat for each line k in txt; etc.
(2) repeat for each line k in fld 1; etc.
For no very good reason, I tend to do (1), but have begun to wonder: for a very lengthy field 1, does my writing to a variable use up more RAM, and so perhaps injure performance? Or is the engine in effect writing to a variable either way? Is a variable read more quickly than a field?
