Thanks to all that answered my email.

I have successfully implemented initializing dynamically menu strings (in mbbo record) by creating a device support C module for a fictitious device.  This gives me access to the mbboRecord structure at IOC init time.  I have chosen INST_IO as link type since its structure is the simplest of all.
Now, the mbbo record is needed only as a menu of choices, where the numeric value of the selected item is used in genSub routine.  The mbbo record never does any IO.
In my xxxx.dbd file I have the following:

 device( mbbo, INST_IO,devMbboSoftMag, "softMag")

The thing is that I was looking for an even simpler solution, but what I did works.
