Re: Find a binary value with CL (V5R4)

Joe:  Care to share an example?

The RTVMBRD command gets me where I initially where I wanted to go 
(thanks Gary and Chuck)  but now I am intrigued by the other fields in 
the API such as Logical vs. physical, etc.

Why I did not think of the RTVMBRD command is beyond me, I got so tied 
up in wanting to use the API I did not think of it.  I also did not 
think to use QADBXREF (thanks Bill)

Thanks.
