Chris -

This was actually the path I had started down and already had the proper masks in place...just wasn't to sure about the shifting part. I had looked into...

The rightmost bit (if set) of each "group" would be 1...ie 8421

...

Thanks for the replies...

Yes the widths are fixed ie . always the first 5 from left, then 13 etc. etc.

I'll play with some of the suggestions and see how...

Sure...Basically I have a large Decimal number ie. 168034788 which I then have to convert to Hex ie. 0A0401E4.....This represents a collection of data which has to be looked at...

Thanks - but I'm only wanting certain bits - see original post...

In this case the answer I'm needing is decimal 10
