uses Strings;

var
  s : string;
  sz : array[0..256] of char;

  s:='.......whatever';
  StrPCopy(sz,s);

The above uses the extended syntax by which the compiler treats PChar and a zero-based
character array as (mostly) equivalent. This is often easier to program. Alternatively:

uses Strings;

var
  s : string;
  b : PChar;

  s:='.......whatever';
  GetMem(b,length(s)+1);
  StrPCopy(b,s);

If you post questions and expect replies then you jolly well ought to check the

        {String to PChar}
        StrPCopy(aPChar,aString);
        {PChar to String}
        aString:=strpas(aPchar);

Note: both functions are in the strings unit.
