using IXF type file for export or load CLOB column

Hi ,

is IXF type file a valid type file for export and load operation on a table with CLOB columns ? I did recently without any error

db2 "export to expreg.ixf of ixf LOBS TO '/home/inst/' lobfile lobs1, lobs2 modified by lobsinfile select * from xxxxxxx_STATEMENT"

db2 "load from expreg.ixf of ixf LOBS from '/home/inst/' modified by lobsinfile insert into yyyyyyy"

OR I have to DEL, ASC ? (db2 v7.2)

I googling and all examples are using DEL

Thank you in advance for your help.
