| Input pin | A pin on a part that receives data. Each part can have zero or more input pins. |
| Output pin | A pin on a part that sends data. Each part can have zero or more output pins. For example, a "Split array" part might have one input pin for an array and two output pins for the first and second halves of the array. |
| Main flow input/output pin | Special input/output pins that are used to pass data into or out of the main flow. These are typically used to pass data between the main flow and external code (e.g. a user interface). |
