In the past I have put it all into one variable with:

set datafileref to (choose file with prompt "Choose the file:")
set file_data to (read datafileref as {text} using delimiter return)

But it doesn't work on a 32MB text file.


What version of AppleScript do you have? Did you mean 32mb or 32k? Older version of AppleScript had a 32k limit. If you're reading 32 _MB_ then you're reading a HUGE file by AS standards, and it will take a VERY long time to parse.

Not a VERY long time in my understanding. In my very limited experience I would say (of course YMMVM) a few seconds if you use the fastest shell tools such as grep, or Satimage osax (ASCII) or Smile (Unicode.) More seconds if you have to use the slower shell tools such as sed awk etc. (in the sense of "et cetera").
