Creation of .xtd file directly?

Hello,

I am a very new user of Materials Studio and a have some limited scripting experience, and I am just trying to make sure I know all of the inbuilt functions of MS. I believe I have explored the help files pretty thoroughly and haven't found what I am looking for - but that doesn't mean its not there! I wonder if anyone can help me with these queries?

1. Is it possible to create an xtd file DIRECTLY from the perl script - ie. Not having to create an arc file and import it? That is, in the same or similar way to creating an xsd file by using the command:
Documents->New("test.xsd");?
I assume not, having had a look at the available scripts in this forum, people appear to have created arc files and imported them.

2. Is there an inbuilt function within Materials Studio that will allow me to convert fractional coordinates to Cartesian coordinates?

3. Is it possible to get user input during the running of a perl script using perls ? Eg getting user input with perl would usually be something like:
#! usr/bin/perl
print "How old are you?";
my \$age = <>;
print "WOW! You are \$age years old!";

but that does not work with MS because there appears to be no command prompt to enter the information! Can you tell me if it is possible?


Thanks so much!
