☜	AUNBLOCK M[UMPS] by Example					☞

Approved for inclusion in a future M[UMPS] Language standard, as a part of the "event processing" extensions.

This command "un-blocks" an event. When an event is "blocked" for a process, that process will not be interrupted to process that event when one occurs. If a registered event occurs for a process while it is "blocked", it will be queued for later processing. If an un-registered event occurs while it is "blocked", it will be ignored. Events are registered by assigning values to nodes in structured system variable ^$Job. Events are "blocked" using the command ABlock.

Note: every ABlock command increases the "block" counter for an event. In order to "un-block" an event, every AUnblock command decreases that counter. Events are only "un-blocked" when the value of that counter is equal to zero.

For examples, see the command ABlock.
