MacMETH is a Modula-2 programming environment for Macintosh computers
(Wirth et al. 1992 ). It consists of a compiler, dynamic linking-
loader, linker, symbolic debugger, and editor. It is very fast and
efficient.

The entire development environment used to fit on a single small
floppy disk (800 KB), which it still would, would you be using
floppies. These days the programmer can still enjoy this efficiency
during development. Thanks to the small size of the compiler and the
dynamic linking-loader, which normally omits any linking at all, edit,
compile, execute cycles are extremely fast. Nevertheless, static
linking is optionally available and double clickable applications can
be statically linked any time.

Thanks to this linking-loader, it is also possible to launch the
symbolic debugger anytime. The execution of the program can be resumed
afterwards. Besides, the language system is so efficient, it could
still be enjoyed on old floppy disk based Macintosh computers. On
current hard disk based systems this means it is blazingly fast. In
the spirit of Niklaus Wirth, this software is not among those that
"become faster slower, than computers become faster!".
