Release 10.1A: OpenEdge Deployment:
Managing 4GL Applications

> ## Developer product requirements and r-code portability

> R-code is portable between any two environments if the following are true:

> - The user interface is the same—MS-Windows or character mode.

> Note: If a procedure contains no code that writes to the screen, its r-code is portable across user interfaces. This is typical, for example, of database schema trigger procedures.

> - The database type (the DataServer or combination of DataServers connected during compilation) is the same.

> - The r-code version is the same.

> - The platforms are compatible (32-bit versus 64-bit).

> For more details about these requirements and how they affect r-code portability, see Appendix B "R-code Features and Functions."
