The language report doesn't say anything about the range of the basic 
types with the exception of BYTE which is defined as the integers 
between 0 and 255. Therefor it is implementation-dependent whether or 
not an integer can be assigned 90909090H. On the other hand it seems 
reasonable to reject the statement b := -1.
