@trekiej and @thread:
Free Pascal Compiler exists for MorphOS, AROS and Amiga/68k. It's open source and free. The classic Amiga version supports the 68020, with optional 68881 FPU (or using a software float library). 68000 support is experimental. It's possible to use most platform-independent high level Pascal language and runtime library elements on Amiga, like lists, hashtables, reference counted strings, and much more. There's also
support for a number of Amiga .libraries directly. (It's trivial to convert a C header to a Pascal one anytime, to add more.)
Beside the command line compiler, the Free Pascal IDE is working on all supported platforms,
including classic Amiga. On MorphOS, the included programmer's editor Scribble includes Pascal syntax highlighting support out-of-box. The FPC AROS support is slightly more advanced and includes fpGUI and LCL (Lazarus Component Library) support as well, thanks to the work of Marcus 'Alb42' Sackrow. It's also easy to use a cross-compiler hosted on Mac OS X, Linux or Windows, targeting the Amiga-like systems.
The upcoming Free Pascal 3.0 stable release will provide official support for the aforementioned Amiga(-like) platforms as well. Meanwhile, experimental nightly SVN builds are available for both 3.0 branch (beta) and 3.1 branch (development/experimental) too
on Alb42's site.
