DString Module Free/ToArray Operations? in Native XDS-x86/XDS-C Posted February 5, 2017 · Report reply DString is Oberon-2. From the docs: "Some library modules are written in Oberon-2, others in Modula-2. In general, any library can be used from both languages. However, do not forget that Oberon modules use implicit memory deallocation scheme and require garbage collection. Refer to the Multilangauge programming Chapter of the XDS User's Guide."
