Rob,

Thanks.  That works great when the disk is too full for the application to 
issue the EXEC to archive the files.  I have to see if we can work that into 
the code.

The major concern I had is to prevent the application from getting the 
following messages when it writes that file that breaks the camel's back:

DMSFRO159E Insufficient storage available to satisfy free storage request from 
0106D6B4
17:37:31  * MSG FROM SCXJXS  : DMSABE152T System abend 0F8 called from 01072580 
while UFDBUSY = 20; re-IPL CMS
HCPGIR450W CP entered; disabled wait PSW 000A0000 00F541B6


And thank you to those who suggested FCOPY and VMARC as well as the minidisk 
and directory solutions.

Jim

I assume there's a pattern in the name or type of the files they
create, so you could do something like this

ACCESS 200 E/E   200904* *

The restrictions of FSTs under the line would apply to the subset that
you make visible with the mask. If
