[J3] Value separators

[Steve Lionel]

Reading CSV files is far more complex than dealing with value 
separators. Fields can be dates, times, currencies and more. Yes, some 
programs that write CSVs offer the option to enclose strings in quotes, 
but many do not. Trying to shoehorn this into list-directed (or even 
formatted) input would be a mistake.

I think that we already have an effective tool for reading CSVs in the 
new SPLIT intrinsic. This has you specify the delimiter(s) you want to 
look for and allows you to make interpretation choices on a column by 
column basis.

As for writing CSVs, that's what we put in unlimited repeat count and G0 
for. Is it perfect? No. But it is a useful tool that satisfies many needs.
