The SessionObject class has the following new attributes:

The ProcessWait attribute is used to specify whether commands executed by the "call system" statement block the execution of the currently running OpenROAD application until they complete. The default value is TRUE, indicating that the OpenROAD application will wait while executing statements via the "call system" statement. A value of FALSE will allow an OpenROAD application to continue executing 4GL statements after issuing a system command via the "call system" statement.

The ProcessWindow attribute is used to specify whether commands executed by the "call system" statement run in a process that has a window. The default value is TRUE, indicating that executing statements via the "call system" statement will create windows. A value of FALSE indicates that system commands run via the "call system" statement will not have process windows.
