I think "local" and "remote" is the best naming, and it'll match the names 
that were used for the fles on FTP_put() and FTP_get() (etc,)

However, keep the subprocedure names the same.  You can rename the 
parameters to be called "local" and "Remote" but the procedure names need 
to be unchanged so that existing code doesn't break.

I agree.   The tricky part is picking an ASCII CCSID that works with every 
possible job CCSID.  819 might work everywhere, I don't know.  Then, what 
happens when a Chinese password has a character that doesn't convert 
correctly to ASCII/819, because it's not in a Latin-1 alphabet?

That's a very good idea.

I agree, but... Be careful with this.  Make sure that we can still set 
every session independently.  In other words, make sure the variable 
you're replacing is one that's not part of one of the session-related data 
structures.
