A scripting engine for network communication software is described. The scripting engine includes a sequencer table and plurality of secondary tables. The sequencer table and plurality of secondary tables provide a table-based command-processing engine to control the functionality of the network communication software. The sequencer table includes commands that are read in a sequential order. The commands are grouped into command types that each defines a specific set of related functionality. Each of the plurality of secondary tables is mapped to a particular one of the command types. Each of the secondary tables includes one or more records containing one or more specific instructions to enable the network communication software application to perform a particular operation indicated by the command, when the network communication software application instructs the scripting engine to process the sequencer table.
