-
- THE INPUT FILE: List of Bulletin Board Systems (BBS's) in Happyville
-
- WHAT WE WANT: The input file lists every type of bulletin board in the
- city of Happyville, so we want to narrow down the list to
- IBM bulletin boards that have file download capability and
- don't charge admission. We also want certain header lines
- retained, to make the report easier to read.
-
- HOW WE DO IT: We maintain a counter (named HDRCNTR) to count the number of
- times a dashed line appears between columns 1 and 11. This
- lets us know when the actual data starts and ends.
-
- While we're within the actual data, we can recognize the
- bulletin boards we want based on the data in specific columns
- of the report.
