CFONB 120 — two accounts (two 01…07 blocks) in one file

One physical CFONB 120 file, two accounts: each is its own 01 (old balance) … 07 (new balance) block, and each balances on its own. The second one opens OVERDRAWN — the old balance carries an overpunched "}" family sign, a debit — and climbs back to a credit of 179.60. A parser that keeps a single running balance across the file, or that reads the sign character as a digit, gets both accounts wrong.

How we know these results hold

Every file in this library is run through the site's own validator on each build. The expected result stated above is asserted by an automated test — if a file stopped matching what this page claims, the build would fail. Two inherited fixtures were repaired this way before publication: three IBANs failed the mod-97 check and several names used characters outside the basic SEPA character set.
