Apart from the fact that TP can't compile Pascal, that shouldn't
compile anywhere.  You can't use NumNode until it is defined, and
it isn't defined until the "end;" is encountered.  Except to
forward define a pointer type.  Thus you need:

  TYPE
    NumNodePtr = ^NumNode;

    NumNode    = RECORD
      Value      : integer;
      pNext      : NumNodePtr;
      END;

Get a Pascal book.
