Hello all,

the Record Reference Manual states that UDF field may be modified and
even is PP. However, whenever I put some value (1) to UDF field of a
passive soft ao record (in order to indicate that the record's value is
undefined now), the record's status / severity do not become UDF_ALARM,
INVALID_ALARM but remain whatever they are. Subsequent queries of the
UDF field give the value 0 insted of 1, although no writes to the VAL
field happen in between.

Using a dbLink with PP property gives the same results.

Looking at aoRecord.c and even dbAccess.c, I found no reason for this.

What am I missing?
