Root include file for Mde Package Base type modules
|
|
|
|
This is the include file for any module of type base. Base modules only use
|
|
types defined via this include file and can be ported easily to any
|
|
environment. There are a set of base libraries in the Mde Package that can
|
|
be used to implement base modules.
