var = LOG(10) REM sets var to1
LOG (number)
Returns the given string as all lowercase .

Returns the natural logarithm of the given number. The LOG function should be used if a common
(base-10) logarithm is required.

Used within a subroutine, LOCAL marks the given variable as valid only within that subroutine.
Variables within a subroutine are accessible anywhere within the program otherwise.
SUB change_var()
LOCAL var
var = 100
END SUB
var = 10
change_var()
REM var is still set to 10
LOCAL
Declares the end of a DO-LOOP statement.

REM Break out of the loop when our seconds are greater than 30
x = DATETIME(SECONDS)
IF (x > 30) BREAK
