Description

The Chains command configures a chain.

Wildcards can be used in truncated paths that are passed into Connect.

{ChainOption} can be:

When modifying a Chain via Connect the Chain will not automatically recompute. The Chains Compute command must be used to recompute following any sequence of Connections, SetComputeTime or AdvComputeOptions commands.

Connections {ConnectionOptions}

{ConnectionOptions} can be:

Connections Add {AddConnectionOptions}

{AddConnectionOptions} can be:

If the new connection being added already exists in the set of connections, the new connection settings for min, max hops, and ParentRestriction overwrites the old values in the set of connections.

Connections Remove {RemoveConnectionOptions}

{RemoveConnectionOptions} can be:

SetComputeTime {TimeOption}

{TimeOption} can be:

AdvComputeOptions {AdvOptions}

The following table describes the options for event detection and step size control. Any or all options can be included on the command line.

OptimalStrand {OptStrandOptions}

{OptStrandOptions} can be:
