One alternative is to use the UTL_FILE package to write an output file. It still imposes a limit on record length, but a larger limit -- 1023 bytes (or is it 1024?) rather than 255.

In one of your other posts you mentioned that you were trying to write records at least 2000 bytes long, so UTL_FILE's limit is still too low. We had the same problem. I wrote a small utility in C to splice short records into long ones. Obviously we needed to adopt some convention to designate which physical record is the beginning of a logical record. It's also something of a nuisance to make sure that the splicing program gets run when it's needed.

Yet another alternative is to use DBMS_PIPE to send your data to another session, run by a program written with embedded SQL. Then that other program can do whatever you need it to do, including writing a file with long records.
