Question about truth value evaluation

Is it allowed to evaluate truth values without comparison operators? e.g.

```
DIM B AS BYTE
B = 0

IF B THEN
    PRINT "true"
ELSE
    PRINT "false"
END IF
```
(B=0 should print "false" and b<>0 should print "true")

or should it always have comparison operator e.g.

```
DIM B AS BYTE
B = 0

IF B<>0 THEN
    PRINT "true"
ELSE
    PRINT "false"
END IF
```
