Thank you Roger, Nick and Maarten.
Maarten - I was wrong in my reply to you. In fact %09.2g did not do anything different from %9.2g. In my rush to reply, I did not read the footnote in the manual [U] 15.5.1, which would have explained it.
Roger - indeed what I wanted (same as the one that I responded to Maarten).
Nick - that was a good work around for omission of leading zeros, would never have thought about it that way.
Regards,
bw
