Extract and Convert Base64 Data from MEDITECH Outbox Message

Extract and Convert Base64 Data from MEDITECH Outbox Message

This is a C/S NPR utility. Run this program from the front end:


;
; Arguments:
;  A = MIS.XO.MSG.urn
;
; This code will retrieve an outbox message, save it locally,
;   then extract the base64 content out of the message and save it to a
;    binary .pdf file
; The file will be saved in the temporary folder pointed to by the outbox message,
;  usually this is: 
;
;  C:\Program Files (x86)\MEDITECH\MagicCS\Data\[UNV]\Ring\[Ring Name]\Temp
;
