IIRC Attachmate and Reflections from WRQ merged, and now is a micro focus product, I use reflections today and you are correct from the top tab (session-ftp client) opens a new window and you can choose how to and what OS to connect to, you don't have to be logged onto the same system you are logged onto via TSO.

IND$FILE is as you said is a command initialed by the client and is basically a screen scrapper, mistakenly hit attention and you can see the data on your screen as its being transferred :)

Assuming I remember correctly, you started FTP by selecting a menu option which opened a separate window.  That window handled the transfer and the resulting status.  TSO was not informed of this action and remained at READY.  And since TSO never knew you were running the FTP, there was no reason to lock up the TSO terminal (i.e. X-SYSTEM).  Now, someone could say locking your keyboard prevents you from, say, doing updates to the same dataset you're running FTP against.  I would expect normal enqueues to prevent that instead of locking you out of the entire TSO session.  Note this was late 1990's and Attachmate is apparently different now.

IND$FILE of course locks up the TSO terminal because it's a command and commands lock you up until they complete.  So my only explanation for Attachmate's action at the time was to make FTP act more like IND$FILE which people were already familiar with... doing a large transfer?  Go get some coffee.

How could it have reported status or completion if it transferred concurrently?

Did it likewise, (for no technical reason) lock up your TSO session during
an IND$FILE transfer?
