In the GTR1 BCC URL there is a field label called NHNLDiff with the Expression imports(1,NHNLDiff,1,0).
The Screen Reference looks like this:
lf-1lp-1h1::iflt(linear(1,ord(1),-1,date2ord(19731217)),0,3,excd.a)et3:styp.a:et10!11!18!48:dspo(1)al252:rank(class.a,permco.a,step3)et1:NHNLDiff:et-999999:StockCount:sum(1,1,step4):PcntNHC252:linear(100,ratio(sum(ifgt(ratio(gprc(1),hgprc(2,251)),1,1,0),1,step4),StockCount)):PcntNLC252:linear(100,ratio(sum(iflt(ratio(gprc(1),lgprc(2,251)),1,1,0),1,step4),StockCount)):PcntNHC252WMA9:ratio(sgwsum(PcntNHC252,0,9,8,7,6,5,4,3,2,1),sgwsum(linear(1,1),0,9,8,7,6,5,4,3,2,1)):PcntNLC252WMA9:ratio(sgwsum(PcntNLC252,0,9,8,7,6,5,4,3,2,1),sgwsum(linear(1,1),0,9,8,7,6,5,4,3,2,1)):NHNLDiff:linear(1,PcntNHC252WMA9,-1,PcntNLC252WMA9)

Can anyone here reconstruct the original GTR1 screen that is referenced? (I'm not even sure this is a legit question.)

Thanks Larry

Add the gtr1 url before the Screen Reference text:

Thanks lizgdal.

I had already tried two iterations of doing what you suggested and got the message that I did not have the permission to do what I was doing. I'll experiment a bit more tomorrow to see why.

I think I left out the question mark.

Permission is needed for Run Screen (a password as detailed in gtr1's response).
It is not needed for Run Backtest or Count.
