I saw that kind of macro-based syntax a long time ago in some ancient Unix code (Version 7 from Bell Labs) - I think it may have been in Bourne's shell ("sh"). It had macros like:

    #define BEGIN {
    #define END }
    ...

The author really seemed to prefer Pascal-like syntax to C.

A quirky programming style that was fairly popular at Microsoft at some point was "Hungarian Notation", invented by Charles Simonyi:
