Re: Find a binary value with CL (V5R4)



fixed

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.
