Thanks to replies received from this group, the bizarre MEDM problem has
been fixed.  As some of you suspected it was in the get_precision 
routine of the High Voltage record code itself.  It was solved by 
one line, and it makes perfect sense.  The actual code is shown below:

static long get_precision(paddr,precision)
   struct dbAddr *paddr;
   long          *precision;
{
   --------------------------------------------------------------------
   The following line was added by Johnny Tang.  Previously, it was 
   calling the routine with an uninitialized value for precision.
   Results were, to say the least, unpredictable.

   *precision=0;

   --------------------------------------------------------------------
    recGblGetPrec(paddr,precision);
    return(0);
}
