then for each new string add 1 to i put "some new data" into newPrefData[i]
then at the end combine newPrefData using tab

Subject: Way to speed up append strings?
I have a preferences file that is fairly large (30K+), and it's created on-the-fly using "append string" functions, e.g.
put "this data and that data..." after thePrefs
put "some more data..." after thePrefs
put "even more data..." after thePrefs
This is getting slower than I'd like, and it appears that the slowdown is because the append functions are getting slow. I'm guessing that RunRev is reallocating memory on each append, then copying the existing string and the appended string into the newly allocated memory. And because I have lots of little appends this really slows things down (and no, there's no way to make the appends longer and therefore fewer...).
My question is this: is there a way to tell RunRev that I want it should start with a big string block (e.g. 64K of memory), when I first create the string?
If not, I'll have to go to a "write to temp file and then re-read from temp file" type of solution (because writing and reading to a temp file appears to be significantly faster than doing lots of little appends).
Thanks, -- Frank
