-One-byte integers default to unsigned, while two-byte and four-byte integers default to signed format.  `OR`ing the format code with `$40` reverses this default, giving signed one-byte integers or unsigned four-byte integers.  (The signed flag is not supported by PRIZM 1.1.3.)

 A pointer to a scalar type (1-10) is indicated by `OR`ing the value’s format code with `$80`. For example, `$82` would be a pointer to a 4-byte integer.
