=== Source code license ===
DN source code was published under the 3-clause [[BSD license]]. However, the code included an implementation of the [[Turbo Vision]] library based on the version from the [[Turbo Pascal]] distribution, and the latter was never released under a license that allows creation of derivative works. In addition,  DN OSP contains modified parts of the [[Virtual Pascal]] runtime library, while the license for Virtual Pascal itself prohibits distribution of modified versions, however, it is not clear whether this applies only to the compiler or to the runtime library too.<ref>{{Cite web|url=https://github.com/unxed/dn2l|title = Dn2l|website = [[GitHub]]|date = 2 February 2022}}</ref>
