Variable names in FreeMarker are basically like variable names in Java
(with a minor difference or two) so you can't have a variable name
that is a number.

Now, you could get at a variable that has a key that is numerical by writing:

${.vars["101"]}

instead of ${101}

but even then you still need for the hash key to be a string, i.e.

input.put ("" + 101, "blah blah");



Use ${.vars[
