Action Messages

CP inserts additional carriage return/line feed (CRLF) characters before some messages that are used, for example, to inform the operator on hardware problems or on the 'intervention required' status of some device. The intention is to attract the operator's attention so the necessary actions can be performed.

All general CP output lines (line type not CP message, MSGNOH, warning or SCIF) that are preceded by at least one additional CRLF character (X'15') or which contain at least two consecutive X'15' characters are treated as a special 'action message' line type CPAMSG. These action messages can be shown with special color or highlighting, and they will be preceded by a plus sign (+) and a consecutive message number. A certain number of these action messages will not be automatically scrolled but will be left pending at the top of the screen. You can specify this number using the FC ACTMSG subcommand, the initial setting is 10. See the FCONTROL ACTMSG subcommand in the z/VM: Performance Toolkit Reference for a detailed description.

Please note that the Performance Toolkit action messages as defined above may not be identical with CP action messages (messages with suffix 'A'), and that only the first line of a two or three line message will usually be treated as an action message (second and consecutive lines are not preceded by an additional X'15'). However, you can let Performance Toolkit treat any other CP output line as an action message by just entering the necessary FC PROCESS command (see Special Line Processing and the FCONTROL PROCESS subcommand in the z/VM: Performance Toolkit Reference).
