AS400 data to .csv problem in Excel

I know many of you have done as400 to Excel using .csv. I'm having a very
strange
problem and could use some help.

Building .csv files in IFS for web users. Users make request thru cgi, clp
builds stmf
to set code page, then cpytoimpf to create delimited file
 CPYTOIMPF  FROMFILE(&CUST6/WWRTN *FIRST) TOSTMF(&URLW1) +
  MBROPT(*REPLACE) RCDDLM(*CRLF) DTAFMT(*DLM) STRDLM('"') FLDDLM(',')
 CPYTOIMPF  FROMFILE(&CUST6/WWRCPY *FIRST) TOSTMF(&URLC1) +
  MBROPT(*REPLACE) RCDDLM(*CRLF) DTAFMT(*DLM) STRDLM('"') FLDDLM(',')

File looks ok in wordpad, except I expected delimiter at end of data, but
these files
only have delimiter at end of each field.
When Excel 2000 displays data, one field, 20 byte number has changed from
,"71010412344005315256", to 7.10104E+19. In fact every number in that column
resulted in the same strange number. (the 20 digit number is certified mail
numbers
and the first 11 bytes are always the same, and MUST be included).
Some other colums, with values like CC, OW, 01, only the 01 is right
justified, zero
suppressed. In both cases the cell format is "general" which I think is
messing it up,
but see no way to set to "text" when building this.

Before we go too far... this process allows any web user to dynamically
select data
to download to their pc. The .csv is the standard for this industry (they
can't spell
XML or anything other than "Excel" or "spreadsheet". Some are reading the
files
in FoxPro. File name is unique every time. Client Access is not an option.
FTP is not. Needs to run, look, feel like any other website with no special
plugins.
Don't know if this is a "feature" of Excel 2000, but that's all we have on
inhouse
desktops to test with. Am at V4R4, fairly recent ptfs. On V4R5 in a few
weeks.
Any help appreciated.
