CSV Format
The previous major version of NOTEFILE (called ADDRFILE) used the CSV format instead of the new NTF format. NOTEFILE cannot read CSV files, so any files created by ADDRFILE in this format must be migrated to NTF format first.
CSV was a very simple format used mainly to store text data. In this format, each card was stored as a separate line in a text file. Lines within a card were separated by commas (or spaces), and optionally enclosed in double quotation marks. Double quotation marks within a line were doubled to distinguish them from the surrounding quotation marks. Spaces and commas that were not contained within double quotation marks were delimiters. Two commas next to each other indicated an empty line within a card, but spaces that appeared next to another delimiter were ignored.
ADDRFILE extended this format by adding a configuration record, compression, and encryption. After compression and/or encryption in ADDRFILE, it was practically impossible to edit the CSV file with a normal text editor.
Note: NOTEFILE will not open CSV files. You need to convert them to NTF format first.
