Decimal from string

How do i get a number thats in a string to a integer variable
e.g.
STR_Number$ = "123"
to
INT_Figure = 123

Normal there is a command for it. Like VAL(STRING)
but i can not find it in Blitz.

Int.

or INT_Figure = "123"

There's automatic type conversion in Blitz.

Thanks for the tip.
