I'm still trying to understand the problem.  You indicate that you had been using V5.6 
ECO5.  Are you saying the problem exists in this version?

Last year I implemented a small application that uses SFTP to get and put files from and 
to a non-VMS system.  I needed to use a batch command file for SFTP since things ware 
happening in a batch job, not from a terminal.  I have not had any problems in either 
direction.  On the non-VMS system I do not know either the system, nor the file format.  I 
suspect some form of Unix as the directory / path structure used "/".

Now, the batch file I use for input to SFTP gets automatically translated into stream_lf 
by SFTP, but as far as I can see, the actual files transfered do not.

The files I transfer all have records of the same length, but are sequential variable 
files on VMS regardless of direction of transfer.

So what I'm trying to understand is, are you having trouble with all sequential variable 
files, or just those files where individual records are of differing length?
