It appears I wasn't clear exactly what we're doing.  Here's what:

Program #1 (on AS/400 #1):  Reads SAVF.  Writes ICFile (?Intersystem
Communication File?), which is set up to communicate to the other AS/400.

Program #2 (on the other AS/400):  Is invoked by the ICF function, and
receives transactions from the 1st AS/400.  It checks to make sure the SAVF
exists on the 2nd AS/400 (and creates it if it doesn't).  Then it writes to
the SAVF on the receiving end.

This totally bypasses SNADS.  And puts all of the responsibility for
retrying communication errors, etc. squarely on your shoulders.  But it's a
LOT faster (I really don't know -how much- faster) than SNADS (which has
error correction and transmission guarantees all over the place).
