The default message file ddname can be changed by using the MSGFILE runtime option. For information about displaying runtime messages for C/C++, COBOL, Fortran, or PL/I routines, see z/OS Language Environment Programming Guide.
Runtime messages provide users with additional information about a condition, and possible solutions for any errors that occurred. They can be issued by Language Environment common routines or language-specific runtime routines and contain a message prefix, message number, severity code, and descriptive text.
CEE3206S The system detected a specification exception.
Language Environment messages can appear even though you made no explicit calls to Language Environment services. C/C++, COBOL, and PL/I runtime library routines commonly use the Language Environment services. This is why you can see Language Environment messages even when the application routine does not directly call common runtime services.
