Note: For the floating-point numeric types SINGLE (default when not assigned), DOUBLE and _FLOAT, the minimum values represent the smallest values closest to zero, while the maximum values represent the largest values closest to ±infinity. OFFSET dot values are used as a part of the _MEM variable type in QB64 to return or set the position in memory. String text type       Type Name       Type suffix symbol Minimum length Maximum length Size in Bytes STRING $            0               2,147,483,647 Use LEN STRING * n $n         1       2,147,483,647 n

Note: For the fixed-length string type STRING * n, where n is an integer length value from 1 (one) to 2,147,483,647.
