This is not correct. Global simple variables are always
initialized. At
least in Delphi it is so:
http://docwiki.embarcadero.com/RADStudio/Tokyo/en/Variables_(Delphi)
<http://docwiki.embarcadero.com/RADStudio/Tokyo/en/Variables_%28Delphi%29>
"If
you do not explicitly initialize a global variable, the compiler
initializes it to 0."
So, Delphi *does* document it. Okay, in that case the documentation needs
to be updated, cause up to now the assumption has been that this is an
implementation detail.
It has always been so in Delphi - at least since I learnt it. The Delphi 7
docs (I can't find older docs online) state it as well:
http://docs.embarcadero.com/products/rad_studio/cbuilder6/EN/CB6_ObjPascalLangGuide_EN.pdf
on page 5-38 "If you don’t explicitly initialize a global variable, the
compiler initializes it to 0." (Docs are at
http://docs.embarcadero.com/products/rad_studio/ )
Please file a bugreport.
Michael.
