When new operator fails in pre-1997 C++.

P: n/a

I've been trying to look up what to do when the new operator is unable
to allocate any memory in pre-1997 C++ (I have managed to get an
answer to this question for current versions.). "Teach Yourself C++"
states that after I use

int *y=new int[6];

I should test with

if (!y).

However, Borland C++ states that, instead of y equalling null, an
exception (xalloc) is thrown, so I'm not sure which is correct. It
also states that I need to #include <except.h> to get the exception
and doesn't state what happens if I use new without that inclusion and
DMA fails.

Can anyone help?
