If you are stuck with trying to import from CSV format, here's a
function that will convert any commas within quotes to another
delimiter character.
function fixQuotedItems tText
-- first make sure that you choose an escape char
-- not contained in your data
repeat for each item escapeChar in "§,•,ª,∞,™,º"
-- or whatever list of odd characters you want
if escapeChar is in tText then next repeat
exit repeat
end repeat
put empty into adjText
set the itemdelimiter to quote
repeat for each line tLine in tText
put 0 into counter
put empty into adjustedLine
repeat for each item i in tLine
add 1 to counter
if counter mod 2 = 1 then
put i after adjustedLine
else
put i into temp
replace comma with escapeChar in temp
put temp after adjustedLine
end if
end repeat
if char -1 of adjustedLine = comma then delete char -1 \
of adjustedLine
put adjustedLine & cr after adjText
end repeat
if char -1 of adjText = cr then delete char -1 of adjText
return adjText
end fixQuotedItems
this will take something like:
a,b,c,"1,2,3,4",d,e
"11,12,13",g,h,i
j,k,"22,23"
and return:
a,b,c,1§2§3§4,d,e
11§12§13,g,h,i
j,k,22§23
You can then parse your data and replace the escapeChar with comma
after you're done.

Thank you, Richmond. Good stuff. That would work here where only
the first to-be item of each line is quoted because it has commas
within it. But if other files have quoted items in other locations
(e.g., the fifth and ninth items), it would mean first identifying
which chunks are quoted before I start converting from commas to tabs.

Hello everyone,
I'm creating an app that imports comma-delimited tables. A few
lines might look like this, where there are 14 items per line.
"Mon, Jan 18 , 2010",9:14 AM,130557,4319,Trade,Buy,X,
135,8.25,10,-82.5,1417.5,20,10
"Mon, Jan 18 , 2010",9:14 AM,130558,4371,Accept,Your ASK,X,

My problem is that Rev treats each date in quotes as three items
rather than one. I convert the comma delimiters to tab by setting
the itemDelimiter to comma and then running the lines through
nested repeat-for-each loops as
repeat for each line thisLine in dataTable
repeat for each item thisItem in thisLine
put thisItem& tab after newLine
end repeat
-- more stuff here
end repeat
I end up with
"Mon (as the first item)
Jan 18 (as the second)
2010" (as the third)
Any suggestions as how I might get the date treated as one item?
Yes, although it is so goofily obvious you have probably thought
about
this one and rejected it:
Change the commas for the bits inside the quotes to something else
( ^
* %) - dunno, any old
thing that isn't a comma . . . :)
