Actually, the majority of currently available Pascal compilers DO support
this operator.  It's often expressed as "@" and is syntactically equivalent
to the "&" operator in C.

And, since we're talking about Apple programming here, there's an alternative
to use of the "New" procedure - you can use the system memory manager.  In 
fact, I recommend that people NOT ever use the New/Dispose/Mark/Release suite;
because there's a pretty large of hunk of library code that gets linked in
to support them.  Just stick with NewHandle and let the ROM do the work....
(This generalization valid for IIgs AND Mac programming.)
