Retrieving the number of records 2

Hi,

How can I know the number of records in an indexed file?

(I'd like to have a progress bar.) (Liant Cobol runtime 11)

Thanks!
 
The only way I know to find the number of records in the
RM Cobol Indexed file is to use the recovery utility which
displays the number of records in the file before it attempts to rebuild the indexes.
 
There was once a Liant utility called RMRECS.COB that did exactly that job. I don't know if it exists now in their site. If there aren't any license issues I could attach it here.

Hope it helps.

Theophilos.

Wooow! thank you very much Theophilos. That is just PERFECT!!

It's just magic!

I've been searching in their site all around, google, yahoo, etc and found nothing about RMRECS.COB

This solution is even better, it's perfect!

I've wanted it for like 2 or 3 years!

Thank You Again!

If there is anything I can do, just ask!

Luis,

Micro Focus (Liant) support could have provided that utility to you for the asking, and still can.

Just go to the support web page and enter a support request. It has recently been updated to return error information.

In the header of the index or relative file, there is information about the file like key descriptions, & counts of alive records & deleted records.

If you read the file as binary file,
position 47-54 contain the number of records in the file (format: pic 9(12) comp-4).
 
RM/Cobol includes the "rmmapinx" utility which also gives the record count, as well as a whole lot of other information about an indexed file. See Appendix G in the RM/Cobol Users Guide.

The program Theotflyos is pretty nice, but personally, I would tend to avoid homegrown solutions like that in case the underlying implementation is changed by the vendor.

Code what you mean,
and mean what you code!
But by all means post your code!
