# to point just one print statement to a text writer:
print to someTextWrite, "hello", foo, bar

# to avoid the new line
print "hello" stop

# musing:
input name
i = 0
input i
input x, y
input 'Enter your choice:', x
# Can you input just a single character?
# If the variable is an int but the input cannot be converted to an int, what happens?
# Can the var be declared with the statement?
input age as int
# Can you target a property?
input customer.name
input obj.count

# FIRST FORM OF INPUT
# Declares new var called name of type int, and assigns user input to it
input name as int  

# Equivalent to:
name = int.parse(Console.readLine)

# SECOND FORM OF INPUT
# Reads a variable that already exists
input num

# Equivalent to:
num = float32.parse(Console.readLine)


# REFINEMENTS

# Many variables could be read at once
input a as int, b as float32

# Properties can be read
input foo.bar              # equivalent to: foo.bar = type_of(bar).parse(Console.readLine)

# A prompt can be specified:
input 'enter an integer', x as int

# Note that we have to write "prompt" if the message is in a variable:
msg = "enter an integer"
input prompt msg, x as int

# A source stream can be specified:
input from source, x as int

input x as int(0)   #  x takes user specified value or 0 in case of error

input x as String ("error"), i(-2)

x as int
while true
    try
         input x
    catch
         print 'try again'
    success
