Could I ask why is there needed VarDataInit ? (only for my interest ;-))
A good question. Formally it is not needed, but in general
initializing variables before use remains a good idea. Here the
TVarData is passed to VarDataCastTo, and after initializing we can be
sure that VarDataCastTo won't find garbage in remaining 4 bytes of
structure if it accesses them for whatever reason.
Thanks for explain
Laco.
