I just discovered that RC4 for Windows does not issue an
error message if one tries to access array element nr. -1

Here's the code I tried:


#declare A = array[1] { 0 }

// No error messages
#declare N = A[-1]; 
#declare A[-1] = 0;

// "Parse Error: Negative subscript"
#declare N = A[-2]; 
#declare A[-2] = 0;


If this is not old news, then can anyone please confirm this ?
