8.113 OSTAILOR (Tailor trace information for specific operating
system)

8.113.1 Function

The OSTAILOR command lets you display or (re-)specify the intended operating system. The effect of
this parameter is to reduce control panel message traffic by selectively suppressing trace messages for
program checks which are considered normal in the specified environment.

The argument QUIET suppresses all exception messages, whereas the argument NULL suppresses
none of them. The other options do suppress some messages and do not supress other messages
depending on the specified operating system.

Prefix values with a plus (“+”) to combine them with existing values or with a minus (“-“) to exclude them
from existing values. See also the PGMTRACE console command which allows you to further fine tune
the tracing of program interrupt exceptions.
