load records split across multiple physical lines; however, it needs to have lines flagged as part of the same logical record, and this has to be done positionally.
Look at the documentation for CONTINUEIF clause of the control file. Sounds like you may have to alter the file (say, with Perl) before loading it into the database. If you're lucky and have the same number of physical records for each logical record, you can use the CONTINUE clause.
