I don't think so, if a Pascal compiler is supposed
to determine "the same type" (exact same type) by looking
at the definition, not the name. Otherwise two compilers
claiming to support ISO Pascal are broken:
program p;
type
T = 1 .. 3;
S = 1 .. 3;
var
x : T;
y : S;
begin
x := y; { fine in Pascal }
end.
This program seems to be Standard Pascal, and compiles.
The corresponding Ada program will not compile:
procedure p is
type T is range 1 .. 3;
type S is range 1 .. 3;
x : T;
y : S
begin
x := y; -- not the same type, compilation error
end;
