Comments
To write comments, use the character #. Any text from this character to the end of the line is ignored. Each line to be commented must be preceded by the # character, i.e. C-like multi-line comments are not allowed.

Functions
The following examples show how to write functions in Macro. A function does not need to have a return value.

# function that takes no arguments
function always_return_5 ()
return 5
end always_return_5
five = always_return_5()
# function that takes an argument and does no type-checking
function add_10_untyped (a)
return a+10
end add_10_untyped
b = add_10_untyped(4)
# function that takes two arguments
function add_two_untyped (a, b)
return a+b
end add_two_untyped
b = add_two_untyped(9, 11)
# function that takes an argument that must be a number
function add_10_to_number (a:number)
return a+10
end add_10_to_number
b = add_10_to_number(6)
# function that takes any number of arguments
function print_all_params
loop arg in arguments()
print(arg)
end loop
end print_all_params
print_all_params(5, 6, 7, 'Hello') |
