5. Control Flow

5.1 Conditionals (If/Else)

Syntax: ( [condition] [body] )

An “if” block is defined by opening a set of parentheses.

= b .
( << b 10
    > "B is less than 10."
)

An “else” block is defined by opening a second set of parentheses immediately after the first block’s closing parenthesis.

= val .
( >> val 10
    > "Value is greater than 10"
)
(
    > "Value is 10 or less"
)

5.2 Loops (While)

Syntax: [ [condition] [body] ]

The block repeats as long as the condition evaluates to a non-zero value.

= count 0
[ << count 5
    > count
    = count + count 1
]
