Yes, I know, it hurts on many fronts. MODS, on the other hand, are a 
clever solution when it comes to session management. Yes, we need to 
switch them around anytime an API is called, but it also simplifies the 
code as one does not need to index all the variables.

The major drawback (and ugliness) of MODS is the fact that one cannot 
access more than one member at the same time. Cannot do stuff like 
Var(I) = VAR(J). This is not a problem with session stuff, though, thus 
I can live with MODS pretty well (while I hate them otherwise).

What I'll miss more are things like var.var.var (multi-level qualifying; 
this really hurts with many APIs; it also prohibits us to put everything 
into a single MODS). I think I'll write both V5R1 and V5R2 code in some 
places, properly IFDEFing it. Thus it can be easily verified that both 
works and at some point we'll throw the ugly code away.

Until we change to V5R4 as well, which will not happen in 2006 (due to 
our customers still partly being on V5R1).

In that case I'll just do some experimenting and testing right now and 
I'll start changing FTPAPI for good once you have your "final" version 
ready. Btw, I very much prefer exchanging code as text files (copy & 
paste using WDSc) as it avoids the hassle with the CCSID of source files.
