+ ; Layman's Explanation: Save the denominator or numerator for ePrescribing for
+ ; each of the patients in the Subfile for that patient in ^C0Q(301,
+ ; Still hard to understand though! Here's a demo:
+ ; ^C0Q(301,IEN has a subfile under node 1 which stores the patients. E.g.
+ ; ^C0Q(301,48,1,15,0)=91$
+ ; ^C0Q(301,48,1,16,0)=93$
+ ; ^C0Q(301,48,1,17,0)=173$
+ ; 
+ ; I store the numerator and denominator under each of the patients. The numerator
+ ; stands for the number of prescriptions that were electronically transmitted;
+ ; the denominator stands for the numbers of prescriptions that COULD HAVE BEEN
+ ; electronically transmitted. End result for Patient 173 is as follows:
+ ; ^C0Q(301,48,1,17,0)=173
+ ; ^C0Q(301,48,1,17,1,0)="^1130580001.3111^2^2"
