writing ifs file-odd specs

Am writing a ascii text file, fixed field length to be ftp'd to a US Post 
Office server.
The following is an exact quote from the specs (Pub 91)
"a line feed and carriage return is needed at the end of every record except 
the last record of the electronic file"

1. I assume it's CRLF, not LFCR
2. I have never heard of leaving off the CRLF from the last record? This file 
is a Header record (130 bytes), followed by Detail 1 (200 bytes), Detail 2 (352 
bytes),Detail 1, Detail 2, etc. No Trailer record. Detail 2 does have a 7 byte 
alpha field at end of record that must contain spaces.

Without final CRLF will ftp have a problem?
