MNOTE statements

An MNOTE statement is included in a macro definition or in the source program. It causes the assembler to generate an inline error or informational message.

An MNOTE appears in the listing as follows:

ASMA254I ***MNOTE***  statement number, severity code, message

Unless the severity code is shown as an asterisk (*), or the severity code is omitted, the statement number of the MNOTE is listed in the diagnostic cross-reference.
