CSV file format
~~~~~~~~~~~~~~~

.CSV (Comma Seperated Value) format is mostly self-explanatory ASCII 
text format.  If you export a file from a database in CSV format and 
look at it you will find that it is simply a list of entries 
seperated by commas:

<CSV_file> ::= { <CSV_line> }
<CSV_line> ::= <value> { "," <value> } <spaces_and_tabs> <CRLF>
<value> ::= <spaces_and_tabs>
        ( 
          { <any_text_except_quotas_and_commas_and_smth_else> }
        | <single_or_double_quote> 
          <any_text_save_CRLF_with_corresponding_doubled_quotas>
          <the_same_quote>
        )

That's all I think... and there is some problem with this format:
different database systems have different definitions of the
term <any_text_except_quotas_and_commas_and_smth_else> :)

Also Paradox version approx.4 has the bug. When converting to
.CSV, it always writes values surrounded by "s -- but if in the 
source database file we have a field containing "s, them will not
be doubled in CSV. 

E.g.: abc"dfg will be translated to "abc"dfg" instead of "abc""dfg".
