If all globals weren't initialized to 0 a lot of code from lots of
people would potentially be in trouble. I've been using Pascal/Delphi
for a very long time. Trust me I know my stuff.
I believe that. I know it is so in practice, but nowhere it says in the
Pascal language specification that this is guaranteed by the compiler.
From the language specification:
Section: Data Types, Variables, and Constants
Sub-section: Declaring Variables
Page: 102
"If you don't explicitly initialize a global variable, the compiler
initializes it to 0."
That should be removed, actually.
