Borland Pascal emulation : mayday, mayday, mayday ! - Gpc

3 Sep 2001


      bonjour,
my question is :
 " is it, in GPC, some replacement for Borlnd's {R+ } ( = range check at
run time, mainly on arrays indices) ?"
I did not find any trace in the GPC manual.
 My trial (see below) where unsuccessful and I need it for my students
...
with thanks, sincerly yours,

===================================
here is the pascal program ::
more inex.pas
program p2;  { 2eme exemple }
{$R+}
const
   Nx = 5;
var
   t : array [1..Nx] of integer;
   k : integer;
begin
for k:= 1 to Nx do
      begin
  t[k] :=  sqr (k)
      end ;
   for k:= -Nx to Nx*2 do
       begin
   writeln (k, "  ", t[k])
       end ;
end .
