a string question

10 Jul 2001

      Hello,

I have a basic question concerning strings and array memory representation
in GPC. To my amusement I noticed that in the following program the string
assigned to an array element cannot be then restored from the array
itself.
So probably an array of strings is not represented in memory just like an
array of simple type, and cannot (?) be simply getmem-ed ?

program test;
type
  NameStr=String[8];
  shortarray=array[1..3] of NameStr;

var
  n:NameStr;
  a:^shortarray;
  i:integer;

begin
 getmem(a,3*sizeof(NameStr));
 n:='12345678';
 for i:=1 to 3 do
  begin
   a^[i]:=n;
   writeln('n = ',n)
   writeln('a^[i] = ',a^[i]);
  end;
end.

As a result the value of a^[i] is an empty string after the assignment;
I will be very grateful for any answers or comments
(I use gpc version 20010502, based on 2.95.3 20010315).
Regards,
Adam Naumowicz
