August 12, 2014
- When you have previously used Stony Brook Modula-2 or ADW Modula-2, it is advised to install and try this new version in a test environment first.
- Before you install this version on a production machine, it is advised to remove any older version first.
- Because of copyright issues, the source code of the implementation modules (MOD files) of the runtime libraries (RTL) has been removed from the package. As a consequence, the RTL libraries also have been protected against modification.
- Tip: if you have been working with modified RTL modules it is advised to save the modified modules.
- The installer will install 2 versions of the compiler and RTL: a UNICODE and ASCII version. The UNICODE version treats CHAR as UCHAR as default for new projects, and all libraries haven been compiled with CHAR as Unicode character. Old projects may not work as expected when compiled with the UNICODE version; but the effort of reworking your projects for UNICODE is rewarding for your software users, especially in Asian countries.
