Hi Robert,

Is it possible to modify links at run time?
I have heard the term re-targetable link mentioned
but am not sure how to implement it.

It has been possible to change soft links (i.e DB or CA links) at
runtime for several years - just modify the INP/OUT/INPA etc. field
using your preferred mechanism (via CA, using a dbpf command from the
console, or even by doing a put from a stringout record).
Since R3.14.8 it has also been possible to change hardware addresses at
runtime, but only if the device support you are using has special code
to handle this. There are no real-world device support layers that I'm
aware of which can do this yet, but the code is available in base to
allow you to if you need it. If you need more information see section
12.5 in the Application Developer's Guide for R3.14.8.
