SAS supplies a set of autocall macros that you can use in your SAS
programs to log messages by using the SAS logging facility. SAS writes
the SAS language logging facility messages to a file using the appender,
FileRefAppender. FileRefAppender is the only logging facility appender
that is available in the SAS language.
You use the following
autocall macros to log messages by using the logging facility:
initializes the autocall
macro logging environment.
defines an appender,
which names the destination of the log message, a message layout,
and a message threshold.
defines a logger, which
defines a message category for log messages and the appenders that
are associated with the message category.
is the log event that
you use to write debug messages.
is the log event that
you use to write trace messages.
is the log event that
you use to write warning messages.
is the log event that
you use to write informational messages.
is the log event that
you use to write error messages.
is the log event that
you use to write fatal messages.
In order to use the
logging facility autocall macros, you must set the MAUTOSOURCE system
option in order to activate the autocall facility. The MAUTOSOURCE
system option is set by default.
