For what its Wirth....

None of our code ass-u-me-s (nor requires) initialization of _our_  
globals (or locals) by any compiler or OS; all of our globals and  
locals are specifically initialized. Helps us survive the shifting  
Macintosh pascal compiler scene with 1988 source code.

Before that I used Pascal at Honeywell, 1978-1988; all variables were  
initialized by their programs, not the OS, not the compiler.
