16.3.1 RDML Functions
The following information assumes the partition is enabled for RDMLX, but all fields, files and functions are RDML and no Components are used.
Extend or Rewrite?
There are two approaches that can be used:
- Extend the existing application. Leave much of the application as is, and create new RDMLX fields, files, components, functions, and optionally Web Pages and Server Modules that utilize existing RDML objects where required. RDML functions can be altered to call RDMLX functions to do Unicode specific processing when no change to the user interface is required. Refer to 16.2 Developing New Applications with Unicode for suggestions.
- Rewrite the existing application. Decide what your main application style will be. Most Alpha fields can be left as is. Change certain Alpha fields to be Char or String (if you need more than 256 bytes). Change other particular Alpha fields to Nchar or Nvarchar if you need to support multiple languages. Add other RDMLX field types as required.
