Hello, this is a general feature when using an uninitialized variable as a VAR parameter.
The compiler cannot know if the called routine needs the parameter values, or if the parameter is only used to return values back to the caller. So, I think, a warning here could be helpful (in the case of READ(LN ) not of course, but in other cases).

It does not need to be. The warning is bogus. This is a bug.
