queries for a set of values

[Susmita/Rajib]

Thank you, Mr. Wong and Mr. Betts, for your crucial inputs. The only
aspect which I find missing is an intuitive GUI and doesn't bother us
with nitty-gritty / intricacies / 'remembering the code bits' of the
CUI / terminal.

Such a GUI system would welcome more users and make the program more
popular among users.

I am considering the options available from your inputs presently.

Thank you once again, and best wishes,
Rajib
