But that would not work after the pointer was used and then it's

So a better way might be:
Always when declaring pointers do it this way:
var p: ^sometype = nil;
Then in stead of using the freemem, define your own procedure:
procedure myfreemem(var p: pointer);
begin if p<>nil then begin freemem(p); p:=nil end end;
Use FreeAndNil() -

FreeAndNil works only for classes, not for objects/record
ReAllocMem(p,0);
Ah, now I understand why you use them :)
Anyway does it set p:=nil ?
