Sirius Mods 6.9

This is a bitmask parameter that controls SirTune. SirTune is integrated with the Sirius Mods as of Sirius Mods version 6.9. The meaning of the bits are:

X'01'

Enables the SirTune data collector. When this is set, the SirTune data collector will look for the SIRTUNED dataset. If present, the SirTune data collector will be enabled, and compilation and sample data will be collected to SIRTUNED. In addition, the MODIFY/SMSG commands will also be available.

The default value of X'01' for SIRTUNE causes the SirTune data collector to be enabled if possible. Things that prevent it from being enabled are the absence of the SIRTUNED dataset and the fact that Model 204 is running under an older SirTune load module. In the first case, the SirTune data collector silently disables itself. In the second case, it issues an informational message and then disables itself. In no case should the default value for SIRTUNE prevent an Online from coming up, so there is probably little reason to set this parameter.

Setting this parameter in an Online not authorized for SirTune will have no effect. For more information about the SirTune data collector, see the SirTune Reference Manual.
