Shortly after the successful upgrade to Arden Syntax version 2.6, Medexter Healthcare announces the completion of implementation of HL7’s Arden Syntax version 2.7. This version features an enhanced assignment operator to allow assignment to individual elements in a list and nested attributes in objects. In addition, the object initialization statement has been enhanced to support assigning to named attributes. Corrections/updates to features introduced in previous versions and a reorganization of the evoke slot chapter are also included. The Arden Syntax compiler by Medexter is now able to process Arden Syntax MLMs written in Arden Syntax versions 2.1, 2.5, 2.6, and 2.7.
