I need to compare the timestamps of all the DBRM members in 2 datasets.

I've a working knowledge of REXX. So I know enough to get a member list from the 1st dataset and then trawl thru it member-by-member and then open the matching member in the 2nd dataset and so on.

The DBRM is an FB80 dataset. I also know (at least I think so) that timestamp always starts at position 25 and is 8 bytes long. But it's not really a text field.
Is it still as simple as reading the 1st line of the file, reading the 1st line of the matching member in the 2nd file and then comparing the substring from the 25th thru the 33rd positions?

Thanks!

if one was generated under the old ebcidc and the second was generated under UTF-8 you could not do it.

but, seems a waste to write a rexx script when a superc compare (ISPF option 3.1?) of the two pds's would suffice.

use the option that only outputs statistics.

if the timestamps are the same, that means the complete dbrm is the same.

use the utility and forget the rexx.

sumithar,

Try this REXX exec to map a DBRM member
