- THE INPUT FILE: "John Doe's List of Things to Do This Week"
-
-
- WHAT WE WANT: Extract from the file only those items that are not yet done.
-
-
- HOW WE DO IT: We ignore any lines that contain a space, X or P in column 2.
- This gives us what we want because:
-
- ─ A space is found in column 2 on all descriptive lines.
-
- ─ An "X" is found there on items that are "Done"
-
- ─ A "P" is found there on items that are "Postponed"
