[[Image:Mod32.png|280px|right]]
A PIM4 compatible [[Modula 2]] and [[Oberon-2]] compiler and IDE for OS/2 that was called just "Canterbury Modula-2" or "MHC Modula-2" even though Oberon was supported as well. Came in two versions, "Regular Edition" for OS/2 Text mode and PM development (Sold for £59 UK or $99 US) and a "Professional Edition" that also allowed SOM/WPS development via a built in direct to [[SOM]] compiler (Sold for £89 UK or $149 US). In addition the company offered a free library for extended compatibility with [[TopSpeed Modula-2]] and sold an assembly coded MATHPAK 87/32 specially adapted to the compiler.
A [[Modula 2]] and [[Oberon-2]] compiler and IDE for 32 and 16-bit OS/2 released by [[Mill Hill & Canterbury Corporation]] in 1998. The compiler was called just "MHC Modula-2" or "Canterbury Modula-2" even though Oberon and Oberon-2 were supported as well, we refer to it as Canterbury Modula-2 to synchronise with the naming conventions used on the later Java compilers from the same company. In addition to PIM4 compatibility, the Modula-2 side of the compiler offers object-oriented extensions similar to Oberon-2.


Note that while the company still appears to have a website it is a personal website of the lead developer, the actual company ceased to exist around 2001 and Mr. Neuhoff no longer offers any support for the compiler and exited the programming tools market altogether around 2010.

A Modula 2 and Oberon-2 compiler and IDE for 32 and 16-bit OS/2 released by Mill Hill & Canterbury Corporation in 1998. The compiler was called just "MHC Modula-2" or "Canterbury Modula-2" even though Oberon and Oberon-2 were supported as well, we refer to it as Canterbury Modula-2 to synchronise with the naming conventions used on the later Java compilers from the same company. In addition to PIM4 compatibility, the Modula-2 side of the compiler offers object-oriented extensions similar to Oberon-2.

The Canterbury Modula-2 compiler was sold in two versions, the "Regular Edition" offered support for OS/2 Text mode and PM development and retailed for £59 UKP or $99 USD while the "Professional Edition" added support for SOM/WPS development via a built-in direct to SOM compiler, the "Professional Edition sold for £89 UKP or $149 USD. In addition, the company offered a free library for extended compatibility with TopSpeed Modula-2 and sold an assembly coded MATHPAK 87/32 specially adapted to the compiler.
