Okay, good luck.  I understand your wanting to keep the paging 
normalized  I'm still a bit confused, though.  If the user switches the 
top, won't that become the "new normal"?  At that point, if you then go 
back to the old style SFLRCDNBR, you'll shift the perceived top, won't 
you?  It seems to me that if you are going to allow the user to change 
the base for the top, then you'll have to basically replicate the 
SFLRCDNBR logic yourself.  Find out which record number of "top" + 
"multiple of page size" is less than the record you wish to display, and 
then put that in SFLRCDNBR.  Then position the cursor using either a 
conditioned DSPATR(PC) or by absolute cursor positioning.
