there're two threads anyway:
"Re: [fpc-devel] Method for write string into TStream" and "[fpc-devel]
Method for write string into TStream"
Anyways, answering DoDi's question.
It definitely won't be able to read a string without a size, but it doesn't
mean that the string size should immediately precede the string content.
So maybe a modification like this could help
procedure TStream.ReadAnsiString(knownsize: Integer=-1)
if knownsize<0 then
TheSize := ...readsize
TheSize := knownsize
