Multiplying an empty string never throws an error

All of these work:

PRINT "" * 2
PRINT "" * "A"
DIM ARRAY[0]
PRINT "" * ARRAY
PRINT "" * -1
DEF NOTHING():END
PRINT "" * NOTHING()
IF FALSE THEN DIM UNTYPED[0]
PRINT "" * UNTYPED

what is it with the IF FALSE THEN DIM UNTYPED[0]? why not just declare UNTYPED?

That's how you make an untyped variable.

IF FALSE THEN DIM TEST1[0],TEST2[0]
TEST1 = 7
TEST2 = "STRING"

HOLY COW! is it possible to make it into a function:

DEF Untyped()
 IF FALSE THEN DIM UNTYPED[0]
 RETURN UNTYPED
END

HOLY COW! is it possible to make it into a function:

DEF Untyped()
 IF FALSE THEN DIM UNTYPED[0]
 RETURN UNTYPED
END

No, it has to be when you create the variable. (And you can't return an untyped variable from a function anyway, that just throws an error)

VAR X=UNTYPED() 'won't work because X is already a number variable

well,
