Changing roll value based on SFLFOLD/SFLDROP

Hi All,

I'm trying to manipulate the SFLROLVAL variable as follows:

When my subfile is in "Fold" mode, I have 3 records of 5 lines showing.
When in "Fold" mode, I want to roll up 3 records at a time.
When the subfile is in "Drop" mode, I have 15 records of one line showing.
When in "Drop" mode, I want to roll up 14 records at a time - i.e., I want
the bottom record on the display to be the top record in the next.

I've attempted to use the SFLMODE keyword on the subfile control to
determine if I'm in "fold" or "drop" mode with success, but when I try to
set the SFLROLVAL keyword (I also have it hidden and protected), I get
nowhere.  The affect of resetting the SFLROLVAL is "one screen too late",
almost as if the read doesn't occur after I press me F-key to change the
mode.

(If I wanted to just let the system control the rolling, it works fine.  But
it rolls a full page at a time.  I want to change the roll characteristics
when I have 15 records to roll up only 14 records.  That's the rub.)

What am I doing wrong?  Any ideas?  Thanks in advance!
