Hi,
I’d use the genericHL7 library and code something like:
set HL7msg [msgget $mh]
set fieldSeparator [crange $HL7msg 3 3]
set subfieldSeparator [crange $HL7msg 4 4]
set orcSegment [getHL7Segment $HL7msg OBC]
set orcField12 [getHL7Field $orcSegment 12 $fieldSeparator]
This would give you the ordering provider in the variable ‘orcField12’.
Hope this helps.
Garry
