Hi, James:
Thanks for the prompt reply.
I am more thinking create my custom composite datatype and then based on the
observation identifier (OBX 3) , kind like what fixOBX5 does. I want to use
the same pattern instead hard code the process for different custom fields.
(I read something about that you can create custom segment, can I create my
own custom data type and get the data from there? Is it a good idea? Sorry
about all these questions, I have not really deeply looked into the source
code yet, but wanted to follow the design pattern.
Thanks
