Accepted message formats
WACS accepts standard HL7 2.3-2.4 delimiters and data types, as defined in this section,
taken from the Health Level Seven Implementation Support Guide for HL7 Standard
Version 2.3.
Delimiters
The interface parses incoming messages for delimiters, and the delimiters might differ in
each message.
This section enables you to select and document which delimiters will be used in your
interface, and to identify related issues early (for example, conflicts with ASCII characters
that have special meaning in EBCDIC).
Note The Acuity System accepts middle initial only (not middle name) in messages.
