MSIR.0885 MSGCTL NOCAN ignored for MSIR.(number)

This message cancels the request. It indicates this sequence:

1. A MSGCTL MSIR.'number' NOCAN command was specified.
2. The MSIR.'number' error message, which normally causes the request to be cancelled, was issued.
3. The NOCAN action was ignored.

Certain error messages should not be changed to NOCAN; doing so will cause unpredictable results. In general, you should not change an MSIR message to NOCAN unless there is explicit documentation explaining the circumstances for doing so. In order to prevent some unsafe MSGCTL NOCAN commands, some error messages will always cause the User Language request to be cancelled. If any of these messages is issued and it has been set to NOCAN, the error message MSIR.0885 is issued, which is a request-cancelling message. Issuing this message will ensure that a SirFact dump is taken, if that is applicable. 

If further, you issue MSGCTL MSIR.0885 NOCAN, SirFact is prevented from intercepting the request cancellation, but the request cancellation happens in any event.
