-

With no sub-options, this disables the output of information-level messages.

-

When error numbers are specified as sub-options, only the output of the information-level messages with the specified numbers will be disabled. Other information-level messages will be output.

-

A range of error numbers to be disabled can be specified by using a hyphen (-), that is, in the form of <error number>-<error number>.

-

Error numbers are specified by the five lower-order digits (i.e. five digits from the right) of message numbers without the prefix "M" (information).

-

Message output from the assembler or optimizing linkage editor cannot be controlled by this option. Message output from the optimizing linkage editor can be controlled by using the lnkcmd option to specify the message or nomessage option of the optimizing linkage editor.

-

If the nomessage option is specified for more than one time, output for all specified error numbers will be disabled.

-

This option is only specifiable for messages with number 0510000 to 0549999 (including the component number).

-

This option can also be used to suppress the output of warnings in the range from 0520000 to 0529999. Specify the numbers of the warnings that you wish to suppress. To suppress the output of other warnings, use -change_message to change them to information-level messages.
