I had faced a similar situation and some time ago I posted a query
for a similar problem. The manual mentions a single register
binding and in some cases a pointer may (two registers)
may be required for binding and the manual does not talk about
such binding. Now that this topic is being discussed, I was wondering if
I can solve my problem!! Thank you.
