boolean function: muss result := false gesetzt werden?

[mjustin]

Lokale Variablen mit Referenzzählung werden immer mit nil (oder '') initialisiert. Alle anderen muss man selber initialisieren.

Zitat:

Local reference-counted* variables are always initialized to nil or '';

Local variables are initialized as if they were passed to the Initialize routine. The Initialize routine uses runtime type-info (RTTI) to zero-out fields (recursively - if a field is of an array or record type) and arrays (recursively - if the element type is an array or a record) of a managed type, where a managed type is one of:

AnsiString
UnicodeString
WideString
an interface type (including method references)
dynamic array type
Variant
