REM Tiny Basic has exactly 26 variables.
REM They start off initialised to zero.
    PRINT A

REM The only data type is sixteen-bit signed integer.
REM They are assigned using the LET statement.
REM Their scope is the whole program.
    LET B = -12345
REM The integer arithmetic operations of  +  -  *  and / can be used
REM and so can the unary negative and positive operators -  +
    LET C = 1 + B - B/5
    LET A = -B
    PRINT "B is ", B
    PRINT "C is ", C
    GOSUB 10

REM The comparison operators =  <  >  <=  >=  <> are available,
REM but their results are not expressions and can only be used in an
REM if statement.
    LET D = 3
    IF D <> 7 THEN LET D = 7
    GOTO D-2
    PRINT "Skip this"
 5  PRINT "Gotos and gosubs can be computed. Beware of moving spaghetti."
    END
10  PRINT "B is now ", B
    RETURN

REM Tiny Basic does not support arrays or pointers. Strings can
REM be used, but only as string constants within a PRINT statement.
