Standard Additions read/write and file extension

Hi list!

I spent several hours today wrestling with something that I don't remember knowing in a previous life, so I thought I'd ask/share. It seems that under OS-X it matters what _extension_ a file has when it is being read using applescript's standard read command.

I was attempting to read return-delimited lines of macroman text by reading "before return" in a loop. If the file is named .dat, the _second_ read starts several characters BEFORE the first return, so the loop never advances past the first return. I couldn't figure out why, so I started building test scripts and eventually discovered that Simply renaming the file to .txt fixes the problem.

Is this a case of applescript being "smart" ? or something else? Obviously, I've figured a way forward for this project, but I can't help wondering.
