In our case with emulated 3380 and Adabas the customer opted to run 
unsupported since they told us they would be off the mainframe in the 2nd 
quarter of 1997. Most of their work was migrated off last year, July, 
except one application that is still in inquiry mode only. I still see TSO 
and batch usage from time to time. I guess you call it the 10 year plan, I 
don't even ask anymore.

Re: Track size and maximum single volume data set size






IMHO 3380 is still in use, in most cases generally because of staff 
lazyness/lack of comptence. 
Yes, I mean it.
AFAIR 3390 was introduced in 1990. 17 years ago. Enough time to perform 
migration.
All the shops I know use 3380 without any real reason. For example they 
use Adabas, however other shops, running the same application migrated to 
3390 years ago. Another examples: JES2 SPOOL, RACF db. No comments.
Of course my experience is limited, that's why I didn't say "in every 
case"; YMMV
