Octo now supports "piece of piece" column definitions, e.g., a column
which is the second "!" delimited piece of the third "^" delimited piece
of a node. An example of this occurs in lab chemistry data in VistA.
Sam Habiel's blog post at
https://yottadb.net/access-vista-lab-chemistry-data-from-octo/ discusses
this, and has a link to Octo SQL for mapping VistA lab chemistry
results.
