The Internal Code Page (-cpinternal) startup parameter determines the internal code page that OpenEdge uses in memory. The code page in which r-code is compiled and the internal code page of the session in which the r-code runs must be compatible. That is, the r-code code page must be either the internal code page, undefined, or convertible to the internal code page.

If the code page of the r-code, from either an operating system file, a memory-mapped procedure library, a standard procedure library, or an archive file is not the same as the session's internal code page, OpenEdge performs an in-memory conversion of the r-code text segments to the session's internal code page.
