EXPORT in DEL forma get SQL3100W in DB2

I am using UDB V8.2 on AIX . When I do an EXPORT in DEL format , it gives a
SQL3100W on certain rows.

mainly, This warning occurs on rows that do not have any columns that are
over 254 chars.

In Command ref on page 365 second paragraph it says that if the char col is greater then 254 and using DEL format only you will get an error. IXF stores data diferently then DEL does, thus not effected by this limitation.
