case

Evaluate the first clause

Given a file named “main.scm” with:

(import (scheme base))

(write-u8
  (case 2
    ((1 2 3)
      65)
    (else
      66)))

When I successfully run scheme main.scm

Then the stdout should contain exactly “A”.

Evaluate the second clause

Given a file named “main.scm” with:

(import (scheme base))

(write-u8
  (case 5
    ((1 2 3)
      65)
    ((4 5 6)
      66)
    (else
      67)))

When I successfully run scheme main.scm

Then the stdout should contain exactly “B”.

Evaluate an else clause

Given a file named “main.scm” with:

(import (scheme base))

(write-u8
  (case 7
    ((1 2 3)
      65)
    ((4 5 6)
      66)
    (else
      67)))

When I successfully run scheme main.scm

Then the stdout should contain exactly “C”.
