Used with the SWITCH statement to list potential routes.

a$ = “Hi”

SWITCH a$

CASE “Hello”:

response$ = “And Hello to you”

BREAK

CASE “Hi”:

response$ = “Hi!” REM this case matches and is used

BREAK

END SWITCH

REM response$ is now “Hi!”

Returns the arc-sine value of the given number.

var = ASIN(0) REM sets var to0

var = ASIN(1) REM sets var to 1.5708 (PI/2)

ASIN (number)

Returns the arc-tangent value of the given number.

var = ATAN(0) REM sets var to 0

var = ATAN(1) REM sets var to 0.785398 (PI/4)

ATAN (number)

Causes an immediate exit from a loop or SWITCH statement.

a = 0

WHILE (a < 10)

a = a + 1

IF (a > 5) BREAK REM the while loop exits once a > 5

WEND

REM variable a is now 6

BREAK

CASE

Returns the ceiling or smallest integer not less than the given number.

var = CEIL(1.2) REM sets var to 2

var = CEIL(4.7) REM sets var to5

CEIL (number)

1 2 ... 8 9 10 11 12 13 14 15 16 17 18 ... 47 48
