If the delimiter is set to a comma it shouldn't treat a space as a delimter as well. Sadly, this is the exact same output as given by Delphi 7. But that still doesn't make it right (Delphi is not immune to bugs), and I don't think FPC should start cloning Delphi bugs too. I read the Delphi 7 help, and there is no mention of special handling when a Space character is involved in the DelimitedText value. So this sure looks like a bug to me.

If the delimiter is set to a comma it shouldn't treat a space as a delimter as well. A space is always treated special. You should either enclose values with spaces in quotes, or set the StrinctDelimiter property to true, in which case the space loses its special meaning. I recommend the second.

In our previous episode, Frank Church said: adapterVals: TStringList adapterVals.Delimiter := ';'; adapterVals.DelimitedText := '192.168.1.2,00:0E:08:E0:7C:ED,Word Space'; adapterVals[0] = '192.168.1.2' adapterVals[1] = '00:0E:08:E0:7C:ED' adapterVals[2] = 'Word' - this should be 'Word Space' Is this a bug or the expected output? If the delimiter is set to a comma it shouldn't treat a space as a delimter as well. This is the expected output and delphi compatible. Hint: set adapterVals.strictdelimiter:=true ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Sure, that is the help for CommaText, not the help for Delimiter or DelimitedText. In the latter documentation it makes no mention of SDF (System Data Format) format usage - which apparently has the Comma or Space character requirement.
