Syntax

    SELECT [ CASE ] Expression

      [ CASE Expression [ TO Expression #2 ] [ , ... ]
        ... ]

      [ CASE Expression [ TO Expression #2 ] [ , ... ]
        ... ]

      [ { CASE ELSE | DEFAULT }
        ... ]

    END SELECT

If no CASE statement matches, the DEFAULT or CASE ELSE statement is executed.

A CASE statement is a list of single values or interval of two values separated by the TO keyword.

### Examples

    ' You want to check the random function of a die.
    ' So you repeat the random function a thousand times
    ' and you count, how many times 1, 2, 3, 4, 5 or 6
    ' have been thrown.

    DIM x AS Integer
    DIM w AS Integer
    DIM a AS Integer
    DIM b AS Integer
    DIM c AS Integer
    DIM d AS Integer
    DIM e AS Integer
    DIM f AS Integer

    FOR x = 1 TO 1000

      w = Int(Rnd(6) + 1)

      SELECT CASE w
        CASE 1
          a = a + 1
        CASE 2
          b = b + 1
        CASE 3
          c = c + 1
        CASE 4
          d = d + 1
        CASE 5
          e = e + 1
        CASE 6
          f = f + 1
        CASE ELSE
          PRINT "This is impossible!"
      END SELECT

    NEXT

    PRINT a, b, c, d, e, f
