Does anyone know how to change the [[HL7 field~|field], [[HL7 segment~|segment], subsegment delimiters used for HL-7 messages emitted from VistA?

Although I'm not sure if it is a good idea to. The HL-7 default is MSH|^~\& The VistA default(at least in the ADT-04 message that is being generated) is MSH^~|\&

^ is used instead of | ~ is used instead of ^ | is used instead of ~

I haven't seen anything the HL-7 menu and a quick scan in fileman didn't turn up any interesting variables.

Thanks, Mike

P.S. Since the MSH is prepended to every message it should be a simple matter for any HL-7 listener to convert tokens accordingly, but apparently it isn't....

Mike go to HL7 Main Menu --> Interface Developer Options --> Application Edit select an application VAFC PIMS for the ADT-04 then change the HL7 FIELD SEPARATOR to | and the HL7 ENCODING CHARACTERS to ^~\&.
