Appendix B - Constant Definitions
In this appendix, the different Constants that are relevant for Module and Business System Developers will be described. Basically, they can be split into three categories:
Manufacturer codes
Module Categories
DataTypes
Manufacturer codes
Each HIMSA licensee is assigned a unique manufacturer code. This code is used to tell Noah:
if the module is from a HIMSA licensee (modules without a valid manufacturer code will not be displayed)
if the licensee already has a module button displayed on the Module Bar
You need to contact Himsa to get a manufacturer code - contact information can be found at Himsa webpage - www.himsa.com.
Module Categories
There are three types of modules: measurement modules, fitting modules and other modules. Upon installation, a module must tell NOAH to which category it belongs.
Constant | Value | Meaning |
mcFitting | 0 | Fitting module |
mcMeasurement | 1 | Measurement module |
mcOther | 2 | Other type of module |
DataTypes
When a module needs to store an action in the NOAH database, it must inform NOAH of the data type of the action to be stored. The currently defined types of data in the NOAH 3 system database are listed below.

Adding new constants
There are two situations where constants can be added to the System Database:
When HIMSA adds a new constant: When a company becomes a HIMSA licensee, HIMSA assigns the company a Manufacturer code.
When a HIMSA licensee submits a proposal for adding a constant in the System Database and the proposal is accepted: A licensee may wish to add a new data type constant that supports a new type of data format.
