Sorry for late.
I read the stackoverflow link you given above. It was about like progressbar. Last two days I explored many sites and learned many things. I'm very interested to learn batch scripting. I read and practice also. But some time I can't understand complicated script as newbie. For example in your script "prompt #$H&echo on&for %%b in (1) do rem" for 0x08 hex characters (you mentioned), to_hs as well as to_HHMMShs section. You set DeltahsVal variable but I couldn't find it's usage in the script.
Shamed to asked foolishly.
