VAQDBIP2 ;ALB/JRP - PDX EXTRACTION UTILITY;16-MAR-93
 ;;1.5;PATIENT DATA EXCHANGE;;NOV 17, 1993
XTRCT(INFOLINE,DFN,RXIFN,ARRAY,ENCPTR,KEY1,KEY2) ;EXTRACT INFORMATION
 ;INPUT  : INFOLINE - Line containing information to extract
 ;         DFN - Pointer to patient in PATIENT file
 ;         RXIFN - Pointer to prescription in PRESCRIPTION file
 ;         ARRAY - Extraction array (full global reference)
 ;         ENCPTR - Pointer to VAQ - ENCRYPTION METHOD file (optional)
 ;                  (only used if encryption will be done)
 ;         KEY1 - Primary encryption key
 ;                (only required if ENCPTR passed)
 ;         KEY2 - Secondary encryption key
 ;                (only required if ENCPTR passed)
 ;OUTPUT : 0 - Extraction was successfull
 ;             Information stored in extraction array
 ;        -1^Error_Text - Extraction was not successfull
 ;NOTES  : INFOLINE is in the format
 ;  <TAB>;;File;Field,Field,...,Field;Multiple Limit;Reverse Order Mult
 ;       : 'Multiple Limit' is the number of multiples to extract
 ;         (defaults to all)
 ;       : If 'Reverse Order Mult' contains a value other than 0,
 ;         multiples will be extracted in reverse order (last in
 ;         first out).  If it does not have a value or is 0,
 ;         multiples will be extracted in normal fashion (first in
 ;         first out).
