Mark a VI as a top-level VI in an LLB so when you launch LabVIEW with an LLB name specified on a command line, LabVIEW opens all the top-level VIs in that LLB. (macOS and Linux) Mark a VI as top level so when you open the LLB from the operating system, LabVIEW opens all the top-level VIs in that LLB.
Top-level VIs are separated by a dividing line from all other VIs in the LLB when you view the LLB contents in the File dialog box. The top-level VIs appear above the dividing line.
Complete the following steps to mark a VI as a top-level VI.
(Windows) You also can double-click a .llb file in Windows Explorer to display the LLB Manager window. Right-click a VI in the LLB and select Top Level from the shortcut menu to mark the VI as top level.
