EXTRACT(MINXML,DFN,OUTXML,MEDCOUNT,FLAGS)  ; EXTRACT MEDICATIONS INTO PROVIDED XML TEMPLATE
 ;
 ; MINXML and OUTXML are passed by name so globals can be used
 ; MINXML will contain only the medications skeleton of the overall template
 ; MEDCOUNT is a counter passed by Reference.
 ; FLAGS are: MEDALL(bool)^MEDLIMIT(int)^MEDACTIVE(bool)^MEDPENDING(bool)
 ; FLAGS are set-up in C0CMED.
 ;
 ; MEDS is return array from RPC.
 ; MAP is a mapping variable map (store result) for each med
 ; MED is holds each array element from MEDS(J), one medicine
 ; J is a counter.
 ;
 ; GETRXS^BEHORXFN(ARRAYNAME,DFN,DAYS) will be the the API used.
 ; This API has been developed by Medsphere for IHS for getting
 ; Medications from RPMS. It has most of what we need.
 ; API written by Doug Martin when he worked for Medsphere (thanks Doug!)
 ; -- ARRAYNAME is passed by name (required)
 ; -- DFN is passed by value (required)
 ; -- DAYS is passed by value (optional; if not passed defaults to 365)
 ; 
 ; Return:
 ; ~Type^PharmID^Drug^InfRate^StopDt^RefRem^TotDose^UnitDose^OrderID 
 ; ^Status^LastFill^Chronic^Issued^Rx #^Provider^ 
 ; Status Reason^DEA Handling
