John,
The correct answer depends on what format of input your third party
software on the AIX box will accept.
Since the hex values for carriage return/line fee/line end/new line
can occur in either Metacode or line data (because of inline resources),
it is not usually a good idea to enable carriage return/line feed
processing on the transfer in any case. This leaves you with two major
choices (not counting proprietary solutions such as Docucorp's
ComCommander or splitter/joiner utilities): 4 byte RDWs or FTP's x'80'
plus 2-byte length field.
I believe (but am not positive) that MVSDownload passes the 4 byte
RDWs for each record along with the data when it is transmitted to the
AIX box. In this case, the 3rd party software would have to be able to
understand that each record is preceded by the standard mainframe 4 byte
length fields (actually, as you know, a 2 byte length field followed by
x'00 00'). Normally, IBM software off the mainframe can handle this
format - indeed, it may require it.
Alternatively, it is possible to set up FTP to transfer the file
binary and "blocked" - which causes each record to be prefixed with
x'80' and a two-byte length field. Again, the presence of the length
field enables software to correctly understand the length of the record
data in the file. Of course, the 3rd party software would have to
understand this format.
So, look at the documentation for the 3rd party software on the AIX
box - it's likely to have a number of switches for various input formats
- and see what fits...this will give you the direction to go in...
Feel free to give us a shout if you have additional questions...

Could we use MVSDownload, as we do with AFP files?
We are sending the lcds files from Zos to be processed by a 3rd party
application on AIX before printing.
Any input appreciated
