1) Don't mix tabs and spaces.
2) Use "python -t" or tabnanny.py (not your eyes) to check for consistent
indentation if you can't live with #1.
3) Post the code you're actually running (e.g., this version is missing a
":" after the "while" stmt, so Python won't run it at all).
4) After the "new_datafile = ..." line, insert
temp_record_id = "Oops! I never gave this a value!! Silly me."
and then see what your program prints <wink>.
