I'm a 69 year old who made a conscious decision 12 years back to leave sales and management and return to my technical roots. Now I'm in a solution architect role where I'm expected to constantly stay abreast of the latest technologies. The pay is good. I don't have to do much coding, but I do some anyway to keep my hand in.

My advice to your Dad is to aim for a job in consulting and analysis rather than coding. Get some certifications in a SaaS platform like Dynamics or Salesforce or whatever. That way he can leverage his business experience and people skills. I've found that people who combine experience with solid knowledge of a software platform get quite a lot of interesting job offers, even if they are older. If he later finds out he has an aptitude and interest in development then he can go down that path after he has mastered the functional stuff.
