# The following script does the same as the previous one
# except that it will write results for phi and psi in a file
# this shows how to do string concatenation,and conversion
# from floating point values to string.
# Then it will open the resulting file so that you see what has been done.
open pdb from download "1CRN.pdb";
$MYFILENAME = "results";
$MYFILE = open file $MYFILENAME in usrstuff for writing;
