Re: subfile processing: SFLSIZ=SFLPAG

David,

You bring up some interesting points.  I, too, have thought of using two
subfiles but in a slightly different manner.

My purpose would be to have the effect of a quick load of the first page
and do background loading of the rest of the subfile.

Way back in the S/38 days there was a trick to give the user a
"perceived" program load time.  All files were conditioned by UC, so the
program would WRITE the first panel, open files, sit on READ.

The only technique I've come up with would have a second program,
running in another memory pool, serve subfile entries via data queue.  I
don't know if you can have a shared open of a WORKSTN file to have a
second job write records.

They second subfile would be for display purposes only.  Size=page. 
ROLL UP/DOWN would read from the background subfile into the display
subfile.

Just another 2 cents.

P.S. I imagine you could have multiple background subfiles and
circumvent the 9,999 record limitation.
