RXXTRCT(TRAN,DFN,ARRAY,CUTOFF) ;EXTRACT PHARMACY INFORMATION
 ;INPUT  : TRAN - Pointer to VAQ - TRANSACTION file
 ;          DFN - Pointer to patient in PATIENT file
 ;         ARRAY - Where to store information (full global reference)
 ;         CUTOFF - Number of days to cut off expired/canceled RXs
 ;                  (defaults to 90)
 ;OUTPUT : 0 - Extraction was successfull
 ;        -1^Error_Text - Extraction was not successfull
 ;NOTE   : If the pharmacy information can not be extracted,
 ;         the "VALUE" and "ID" nodes in ARRAY will be deleted.
 ;       : If TRAN is passed
 ;           The patient pointer of the transaction will be used
 ;           Encryption will be based on the transaction
 ;         If DFN is passed
 ;           Encryption will be based on the site parameter
 ;       : Pointer to transaction takes precedence over DFN ... if
 ;         TRAN>0 the DFN will be based on the transaction
