A CSV file will have double quotes in if the data contains the delimiter, consider:
Somevar,Somethingelse,A line with a comma, in,something else
If that is read in the "A line with a comma, in" actually looks like two variables as the comma delimiter appears in the string. To counteract this, SAS (and all other implementations such as Excel) will quote that string to look:
Somevar,Somethingelse,"A line with a comma, in",something else
So it is clear that the comma there is part of a text string not a delimiter. This is standard behaviour, and if your data contains the delimiter, then that should be how it is presented.
