# Procs
Procedures in Nimrod are declared using `proc` and require that their parameter and return types be annotated. After the types and parameters, an `=` is used to denote the start of the function body.
Procedures in Nimrod are declared using `proc` and require that their parameter and return types be annotated. After the types and parameters, an `=` is used to denote the start of the function body. Another thing to note is that procedures have uniform function call syntax, which means that they can called as both `foo(a, b)` or `a.foo(b)`.
``` nimrod
proc fibonacci(n: int): int =
if n < 2:
result = n
else:
result = fibonacci(n - 1) + fibonacci(n - 2)
result = fibonacci(n - 1) + (n - 2).fibonacci
```
