Tunnel Appearance
| Tunnel Type | Appearance |
|---|---|
| Non-indexing (for array types, the entire array enters the loop) |  |
| Indexing (for 1D array types, the array enters the loop one element at a time)
(for 2D array types, the array enters the loop one row at a time) |
 |
| Tunnel Type | Appearance |
|---|---|
| Indexing (for scalar elements, a 1D array of the elements is built up on the loop border)
(for 1D arrays, a 2D array of the rows is built up on the loop border) |
 |
| Last Value (the value generated by the last iteration of the loop is output by the tunnel) |  |
| Concatenating (for 1D arrays, the value generated by each loop iteration is concatenated onto the end of the previous value, resulting in a tunnel output of all the individual 1D arrays concatenated as a single 1D array) |  |
| Conditional (for scalar elements and a Last Value tunnel, the tunnel will output the last value where a TRUE was wired to the conditional tunnel)
(for scalar elements and an Indexing tunnel, the tunnel will output a 1D array containing all loop iteration values where a TRUE was wired to the conditional tunnel) |
 |
| Shift Register |  |
| Tunnel Type | Appearance |
|---|---|
| Linked Tunnels (when new frames are created, wires are automatically created between linked tunnels) |  |
| Use Default if Unwired (for frames that do not have a wire sourcing this output tunnel, the default value for its datatype will be used if that frame executes) |  |
