That depends on how you have it genned.  We have ours going to TPX.  I don't
know if you can get to VTAM; we have not been able to do that yet.  I have
heard (but don't know) that there is a problem with this working through the
3172 we have to do the actual physical link (some piece of the whole doesn't
work through that device).  That deficiency isn't a big deal for us, but it
is important to know.

PDS's look like directories.  You see your own "home" directory on the MVS
system.  You can use "get" and "put" just like you would with any other
system.  The syntax works exactly the same as you would expect from a Unix
site (ie: you CD to the PDS, and get or put the members).

"BINARY" mode will transfer images.  "TEXT" will attempt ASCII <> EBCDIC
conversion.

One note:  If you're putting files to MVS, there's a default allocation
space issue to be aware of.

Do it... 

None of this means anything when V2 comes out, sometime this summer I've
heard.  Version 2 is resident in the kernel (V1 is not).
