I must apologize for a typo in my previous message. 1=0 does give the
correct answer. 0=1 gives the incorrect answer.

Geoff,

We noticed some changed behaviour in calc and calcout records from

v3.13.4 to v3.14.6 and were unable to identify the cause. Take a

simple

calc record, maybe too simple:

record(calc,"CTL_TEST_66/CALC") {

field(CALC, "1=0")

field(SCAN, "1 second")

}

In v3.13.4 VAL is the expected value of zero. In v3.14.6 VAL is one.

The same applies for the calcout record.

I am unable to reproduce your problem.  I put your .CALC and .SCAN
fields into a calc record in one of my databases.  VAL=0 as expected.
This is 3.14.6 on Linux.
