AS I understand, there are in sdfdata.pp:
TFixedFormatDataSet - for SDF = "(*S*tandard *D*ata *F*ormat) A simple
file format that uses fixed length fields."
TSdfDataSet - for variable field length, where fields are delimited by
Delimiter (and probably quoted) ... we can call it "CSV" and here we can
follow http://tools.ietf.org/html/rfc4180 (with exception, that field
delimiter can be user defined - .other than comma)
It will be good also document in begining of sdfdata.pp what standard is
followed ;-)

Finally, I'll post on the forum that sdf compatibility is not one of the
goals of sdfdataset.
Is there some defined on-disk format that sdfdataset should be following?
As I understood it, it is either fixed length or CSV. CSV as in
http://tools.ietf.org/html/rfc4180
People can only go by what they see (they can't read your mind when you
committed sdfdataset).
There is:
- the unit name ("sdfdataset")
- the comments
- the code
- the output
All of this makes it in my opinion more likely to be SDF than CSV.
CSV is not SDF.
See the test results from the Delphi test I posted to the list earlier.
For a description of what SDF is (based on Delphi help as well as the
tests), see
http://wiki.lazarus.freepascal.org/SDF
If you understand it is CSV, why not document it, even if only in a readme:
In contradiction to what its name may apply, Sdfdataset reads and writes
CSV data according to RFC4180, not the Delphi SDF format.
PS: I'll leave writing a test set to test against RFC4180 for people who
care.
