Input Boolean value port that signals an update of input data and stream parameter specifications. The new specifications are pulled from the InStreamPolicy or InDataPolicy ports (or both) if these ports are connected. A false Boolean value is ignored.

Input string value port that allows new stream parameter specifications to come in when an update signal is received. The format for specifying the value is as follows:
Lazy Loading==BooleanValue
where BooleanValue is either true or false.

Input string value port from which the new input data specifications are pulled when an update signal is received. The format for specifying the value is as follows:
class==dataStreamClass;File Path==filePathValue;Variable Name==variableNameValue where:

It is not necessary to specify all arguments for the input string value. For example, if you want to continue sampling from the same data set but change the column from the data set, then you can specify a string for the InputDataPolicy port that contains only the Variable Name==variableNameValue option.

Output string value port for text values to be pulled.

This area provides fields for modifying the input data specifications associated with the Text Source block. The File Path field specifies the absolute or relative file path for the input SAS data set or JMP data table file. The Variable Name field identifies the variable or column name in input data file. The Load from Remote SAS Workspace Server checkbox indicates whether the input SAS data set file is to be loaded from the remote SAS Workspace Server host.

This area provides fields for modifying the stream parameter specifications that control how the stream of text values from the Text Source block is prepared. The field Lazy Loading is Boolean. If the Lazy Loading field is false, the input data set file has to be loaded at the start of simulation. Otherwise, the data file is loaded only when its contents are needed during simulation.

This option resets the current data set back to the first observation when a true Boolean value is received at the InUpdate port. If the InDataPolicy port is also connected and a new data set is specified, then the new data set starts at the beginning with the first observation if the Reset Sampling at Update option is selected.

DataStreamDescription (text), InputDataPolicy (text), ResetStreamAtUpdate (Boolean)
The format for specifying the value of the InputDataPolicy factor is as follows:
class==dataStreamClass;File Path==filePathValue;Variable Name==variableNameValue
where:

The format for specifying the value of the DataStreamDescription factor is as follows:
Lazy Loading==BooleanValue
where BooleanValue is either true or false.
