RE: DOS: A newbie question about get()

I think the documentation explains very well the advantages of using 
get():

"get() can read arbitrarily complicated Euphoria objects. You could have 
a long sequence of values in braces and separated by commas, e.g. {23, 
{49, 57}, 0.5, -1, 99, 'A', "john"}. A single call to get() will read in 
this entire sequence and return it's value as a result."

"The combination of print() and get() can be used to save a Euphoria 
object to disk and later read it back."

So I wouldn't use it to read from the keyboard but rather from a file 
that was written using print().  I like games so I find this to be the 
easiest way to write and store a high score table or saved game stats 
for instance.  You don't have to worry about the details of reading in 
your data.  You get() back exactly what you print().
