Array that has zero elements but has a defined data type. For example, an array that has a numeric control in its data display window but has no defined values for any element is an empty numeric array.
enterprise
A business or organization.
EOF
End of file. Character offset of the end of file relative to the beginning of the file (that is, the EOF is the size of the file).
error cluster
A LabVIEW data structure that can contain information about errors that occur during program execution. See also Error Handling.
error handling
Taking action, in a software program, as a result of errors that occur during program execution.
event data node
The node on the left side of an Event Structure's event case, which contains event data. See also: Event Structure, Event Filter Node.
event filter node
The node on the right side of an Event Structure's event case, which is available only for Filter Events and is used for writing filtered event data or for discarding the event.
event structure
A LabVIEW structure used for capturing user interface and dynamic events.
event-driven programming
A style of programming that waits for events to occur (for example, using an Event Structure), rather than repeatedly testing (polling) for data conditions to change.
execution highlighting
Feature that animates VI execution to illustrate the dataflow in the VI.
expandable node
Refers to a subVI or function that can have a variable number of inputs and outputs at edit time. The number of inputs and outputs can be shown or hidden by resizing an Expandable Node vertically.
Express VI
A subVI designed to aid in common measurement tasks. You configure an Express VI using a configuration dialog box.
expression node
A node that is similar to a Formula Node, but having only a one-line, single variable formula (expression).
