This extra code block adds brackets at the same indentation level as the switch statement itself which can hinder readability of the code. Thus, move the variable "val" declaration and definition at the top of the function where other variables are already present, and remove the extra code block from within the select statement. This also is the preferred style in the PCI tree.
