Hello GKS Xperts
I have a small problem with the coordinate systems .
When my program reads the locator position instead
of the position i.e x and y coordinates being in
world coordinates ; they are in device coordinates.
Please enlighten me as to how to get the program output
world coordinates instead of either DC or NDC coordinates
I am using the subroutine GRQLC(wkid,lcdnr,stat,tnr,px,py)
where px and py are supposed to be in world coordinates but
my program returns device coordinates.

Thanks in advance 
Have Fun
