The succ returns the ordinal value that is the successor of the parameter passed to it. It is an error if the parameter does not have a succssor. The type of the value returned by this function is always the same as the type of the parameter.
The succ function's only parameter is an expression of ordinal type.
succ(false) returns true
succ(21) returns 22
succ('A') returns 'B' (assuming the ASCII or ANSI character set)
