>From the context in which you ask, I'd guess something "strange and
wonderful" occurs; but I've been too long away from "serious" 3270
datastream coding to remember anything unusual about SBA addresses
ending with the values you cite. Of course, I'm "ass.u.ming" you follow
the SBAs immediately with SF[E] orders....
