Hi,

I asked a question about a compiler hint in the fpc-users mailing list.
As JoshyFun suggested, is it not maybe better to change FillChar()
definition so first parameter is a out parameter - to prevent
unnecessary compiler hint in code?

Hello Graeme,

Insert this, or in other words "use it". The reason is that "fillchar"
first parameter is "var" instead "out".

Temp[0]:=0;

GG>   FillChar(Temp, SizeOf(Temp), 0); // <-- I added this to no affect
