I have a BOY "Choice Button" with its PV set to "$(dev):RangeStr"
My 'range' PV is between 1 and 8 with a corresponding ENUM string of 8 also.
The widget works fine in that it sets the 'range' on selecting the ENUM
but when I do
a write to the 'range' from elsewhere, the 'range' is set to the value
but my ENUM widget it not.
I then added the '$(dev):RangeENUM' record so that whenever a
'$(dev):range' is done, a FLNK updates my widget as well.
This works as I would want it to be I'm sure there is a better way (not
having 2 mbbo records ie).

###############################################################
  record(ao,         "$(dev):range")  {
     field(DTYP,   "asynInt32")
     field(PINI,   "YES")
     field(OUT,    "@asyn(int32 $(addr) 1.0) reason(2)")
     field(FLNK,   "$(dev):RangeENUM PP")
  }

  ##  ENUMS for 8 Ranges #####################################
  record(mbbo, "$(dev):RangeStr") {
     field(DTYP, "Soft Channel")
     field(OUT,  "$(dev):range PP")
     field(ONVL, "1")
     field(TWVL, "2")
     field(THVL, "3")
     field(FRVL, "4")
     field(FVVL, "5")
     field(SXVL, "6")
     field(SVVL, "7")
     field(EIVL, "8")
     field(ONST, " 1  :  10 mA")
     field(TWST, " 2  :   1 mA")
     field(THST, " 3  : 100 uA")
     field(FRST, " 4  :  10 uA")
     field(FVST, " 5  :   1 uA")
     field(SXST, " 6  : 100 nA")
     field(SVST, " 7  :  10 nA")
     field(EIST, " 8  :   1 nA")
   }

  record(mbbo, "$(dev):RangeENUM") {
     field(DTYP, "Soft Channel")
     field(OMSL, "closed_loop")
     field(DOL,  "$(dev):range")
     field(OUT,  "$(dev):RangeStr PP")
     field(ONVL, "1")
     field(TWVL, "2")
     field(THVL, "3")
     field(FRVL, "4")
     field(FVVL, "5")
     field(SXVL, "6")
     field(SVVL, "7")
     field(EIVL, "8")
   }
