varsha,
the best way of writing scripts that do what you want to do
is to follow two steps:
1) learn the tcl language first. tcl 8.5 now comes with a very nice
tutorial. http://www.tcl.tk/man/tcl8.5/tutorial/tcltutorial.html
... and take your time. it will be worth it.
2) follow the VMD scripting tutorials. they contain examples and
solutions and you'll learn how to think the "VMD way".
rushing ahead will get you a solution to those - rather trivial -
problems faster, but you won't really learn that much and once
you move up to more complicated scripts, you will really appreciate
having learned the fundamentals well. debugging tcl is not trivial
but a good knowledge of tcl avoids an enormous amount of bugs.
cheers,
axel.
