A slot is a place or position where something can be fitted. For example, a slot on a computer motherboard is where an expansion card can be inserted.
In a slot machine, a person inserts cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode into a designated slot on the machine. The reels then spin and stop, displaying symbols according to the machine’s pay table. If the symbols line up on a winning payline, the player receives credits based on the payout value listed in the pay table.
The pay tables for many slots include a picture of each standard symbol and how much the player can win for landing them on a pay line. In addition to this, some slots also list special symbols and their associated payout values.
Series slots that are used to store data for a specific run index and display this in an SCT can be shown in either the Slot Dialog or the Slot Viewer, depending on how they are configured. They also have special ornamentation in the column headings to indicate their periodic input mode. To move a serial slot from the viewer to the slot dialog, simply drag it. Similarly, to move a slot from the dialog back to the viewer, drag it onto the slot icon on the SCT. There is one slot per timestep for each model, and each model can contain multiple Slot Dialogs and multiple Slot Viewers.
