Source	Generates agents.
	Sink	Disposes of incoming agents.
	Delay	Delays agents by the specified delay time.
	Queue	Stores agents in the specified order.
	SelectOutput	Forwards the agent to one of the output ports depending on the condition.
	SelectOutput5	Forwards incoming agents to one of the five output ports depending on (probabilistic or deterministic) conditions.
	Hold	Blocks or unblocks the agent flow.
	Match	Finds a match between two agents from different inputs, then outputs them.
	Split	Creates one or more copies of each incoming agent (“original”).
	Combine	Waits for two agents, then creates a new agent from them.
	Assembler	Assembles a specified number of agents from multiple sources (5 or less) into a single agent.
	MoveTo	Moves an agent from its current location to a new location.
	ResourcePool	Provides resource units that to be seized and released by agents.
	Seize	Seizes the number of units of the specified resource needed by the agent.
	Release	Releases resource units previously seized by the agent.
	Service	Seizes resource units for the agent, delays it, and releases the seized units.
	ResourceSendTo	Sends a set of portable and/or moving resources to a specified location.
	ResourceTaskStart	Defines the start of the flowchart branch that models the task process for resource units (usually it is a resource preparation process).
	ResourceTaskEnd	Defines the end of the flowchart branch that models the task process for resource unit(s) (usually it is a wrap-up process).
	Downtime	Defines either maintenance, repair, or any other type of activity that interrupts normal resource tasks for resources specified in a ResourcePool block.
	Enter	Inserts agents created elsewhere, into the flowchart.
	Exit	Accepts incoming agents.
	Batch	Accumulates agents, then outputs them contained in a new agent.
	Unbatch	Extracts all agents contained in the incoming agent and outputs them.
	Dropoff	Extracts the selected agents from the contents of the incoming agent.
	Pickup	Adds the selected agents to the contents of the incoming agent.
	RestrictedAreaStart	Restricts the number of agents in a part of the flowchart between this block and the corresponding RestrictedAreaEnd block.
	RestrictedAreaEnd	Ends an area started with the RestrictedAreaStart block.
	TimeMeasureStart	TimeMeasureStart and TimeMeasureEnd form a pair of blocks that measure the time spent by agents between them, such as “time in system”, “length of stay”, and so on. This block tracks the time point at which the agent has gone through.
	TimeMeasureEnd	TimeMeasureEnd and TimeMeasureStart form a pair of blocks measuring the time the agents spend between them. For each incoming agent, this block measures the time it has spent since passing through one of the corresponding TimeMeasureStart blocks.
	ResourceAttach	Attaches a set of portable and/or moving resources to the agent.
	ResourceDetach	Detaches previously attached resources from the agent.
	PMLSettings	Defines some auxiliary settings either related to all library blocks or configuring the behavior of some blocks.

	Wait	This block is like the Queue block with one exception: it supports manual freeing (you must call free() or freeAll()). It has no order (except in the case of preemption occurs, if the latter is turned on).
	SelectOutputIn	Both with SelectOutputOut act as two halves of a large multi-exit SelectOutput block.
	SelectOutputOut	Both with SelectOutputIn act as two halves of a large multi-exit SelectOutput block.
	PlainTransfer	A place to write some action when agent passes through some point of your flowchart.

Although these blocks are legacy, they are fully functional and supported for backward compatibility. However, there are newer blocks with similar functionality that offer more versatility and flexibility, so consider using them:

• Store, Retrieve, Storage System and library-specific space markup shape (Storage) to model warehouses and storages.
• Use other blocks from the Material Handling library to model conveyor systems.

	RackSystem	Models a storage zone containing a set of racks (defined by PalletRack shapes), providing centralized access and management of racks.
	RackStore	Places an agent in a cell of the specified rack (PalletRack) or storage zone (RackSystem).
	RackPick	Picks an agent from a cell of a rack (PalletRack) or a storage zone (RackSystem) and moves it to the specified network node.
	Conveyor	Moves agents at a specified speed, maintaining order and space between them.
