Demonstrates a simple counter with theme toggling using Falcon variables and functions.

a := 0
b := 1
print(a)
print(b)
for i in 1..8 {
    c := a + b
    print(c)
    a = b
    b = c
}

Generates first 10 Fibonacci numbers.

func fact(n) {
    if n == 0 { return 1 }
    return n * fact(n-1)
}
print(fact(5))

Calculates factorial of a number recursively.

func isPrime(n) {
    if n < 2 { return false }
    for i in 2..n-1 {
        if n % i == 0 { return false }
    }
    return true
}
print(isPrime(13))

Checks if a number is prime.

nums := [1,2,3,4,5]
sum := 0
for n in nums { sum += n }
print(sum)

Calculates the sum of an array of numbers.

s := "HELLO"

print(f)

Converts Celsius to Fahrenheit.

temp := 80
thresh := 75
if temp > thresh { print('Alarm: Temperature Too High!') } else { print('Temperature Normal') }

Simulates an alarm if threshold is exceeded.

steps := 10
pos := 0
for i in 1..steps {
    pos += if rand(0,1) < 0.5 then -1 else 1
    print(pos)
}
