To read such a file, you need to do q4 dump analysis.

I had a doc that I was posting that was shall we say a no-no. Here is the document id and link, so if you have a software contract you can read it.

See my post in the above thread.

OZBEKBRC00000611 - How do I use q4 to pre-process a dump that HP needs to read

I'm working on a paraphrase of the document, but you'll have no trouble reading it if you have a software contract.

Dan G. has been kind enough to leave my version out there for the time being. I will get my paraphrase approved and posted as soon as possible.

Hi Steven,

Actually what I am trying to do is write a utility similar to adb.I want write a program which will accept an address and print value stored at that address.adb does this by following command.
adb>440C4000 /2X.
That's why I am trying use cr_open and cr_read but I don't know how to convert this address to page number. which is needed by cr_read.
