Richard Dickson reported:

    TJNAF uses a locally developed record whose get_precision function
relies on the passed paddr->pfield to point to the field for which
precision is being requested.

In 3.13 there is a better way to determine the field.
A new routine

int dbGetFieldIndex(struct dbAddr *paddr);

is available. In addition the generated .h file
has a #define for each field. For example
the aiRecord.h has definitions:

#define aiRecordNAME    0
#define aiRecordDESC    1
#define aiRecordASG     2
#define aiRecordSCAN    3
#define aiRecordPINI    4
#define aiRecordPHAS    5
#define aiRecordEVNT    6
#define aiRecordTSE     7
#define aiRecordTSEL    8
#define aiRecordDTYP    9
#define aiRecordDISV    10
...

Thus you can use statements like

  ind = dbGetFieldIndex(paddr)
   if(ind==aiRecordVAL) ...
or use switch statements, etc.

Note that dbGetFieldIndex does NOT use pfield to determine
the index.
Does this solve your problem?
