Files

• GNU Pascal no built-in Assign procedure for files, but you can write it by yourself using the "Bind" mechanism of Extended Pascal:

    Procedure Assign ( Var T: Text; Name: String );
  
    Var
      B: BindingType;
  
    begin (* Assign *)
      unbind ( T );
      B:= binding ( T );
      B.Name:= Name;
      bind ( T, B );
      B:= binding ( T );
    end (* Assign *);
  

• GNU Pascal has no untyped files, "BlockRead", or "BlockWrite".
