There is no change delta within a CP or on one-shot sets.
Thus, ::BLK.PARM := .00001;
Will always result in the value changing (assuming that the parameter is
accessible)

Sascha,
If the changes that are being written are small, make sure that the change
deltas are set to appropriate values. If you are looking at the detail
screen to see the RI000Xs, you might want to call the display up again to
make sure that you are seeing the most recent results.
If the value changes being written are large then ignore all that.
If a SEQ block can't write to a parameter it will get an operational error,
but if you have exception handlers running, sometimes these are set to keep
going, so you might want to check that.
Regards,
David
