My vote is 'no'. This is either a GNU extension or an error. It is certainly not a legacy issue as array constructors simple cannot appear old moldy *legacy* codes. I would be in favor of making it a hard error. If you believe gfortan must be able to compile invalid source, then add an option such as -fallow-invalid-scalar-character-entities-in-array-constructor. $0.02 -- Steve
