This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The StepSubsystem property controls job enumeration methods, filtering for any jobs with any step defined to use the subsystem specified.
object .StepSubsystem [= value]
An expression that evaluates to an object in the Applies To list
A string that specifies a SQL Server Agent job step subsystem by name

SQL Distributed Management Objects (SQL-DMO) strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString.
Most commonly, a job step will use either the ActiveScripting, CmdExec, or TSQL subsystem. Other job step subsystems exist. Job step subsystem names can be enumerated using the EnumSubSystems method.
