Switch off a class of messages:

Quiet all messages except for General::infy:

Normally two messages would be issued:

Quiet constructs can be nested:

Use Check and Quiet to provide values for arguments where a function is not applicable:

Without the Check and Quiet, the middle input would have returned unevaluated with a message:

Define a function that enables messages locally, even when inside an outer Quiet:

Normally Quiet suppresses messages:

Using unQuiet restores messages locally:

Messages inside Quiet but outside unQuiet are still silenced:

If Quiet is used inside Check, messages suppressed by Quiet are not tested by Check:

However, the operation of Check is not affected by being inside Quiet:

When Quiet is nested, inner on and off lists override outer ones:

Messages that have been turned off by Off are not turned on by the third argument of Quiet:

Compare with:

Quiet suppresses messages during the evaluation:

It does not quiet messages that occur during formatting:
