Most of our compilers (including C compilers) are written in Pascal.

There are two reasons. The strong type checking in the Pascal compiler I
use is an important part of development productivity.

The second reason is Pascal has features that make it well matched to
the implementing a compiler. Pascal's fundamental support for string,
sets and boolean support tends to be very useful and natural to use.  We
regularly use expert systems as part of our code creation process. Our
experience has been that they are easier to implement in Pascal than C.

The final point is an area of personal preference is the scoping
support for local functions.
