Idiom for initialising a sub VI?

[aputman]

From documentation for the FOR loop:

The count terminal specifies the number of times to execute the code inside the For Loop. If you wire 0 or a negative number to the count terminal, the loop does not execute.

Your way works.  I've just never seen it done that way before.  Perhaps using constructs that people will immediately recognize is worth something to you?

Hej GerdW!

Have you any reference to this in the documentation of LabVIEW?

Default Data in Loops

Loops produce default data on the first iteration when the shift register is not initialized.

For Loops produce default data if you wire 0 or a negative number to the count terminal of the For Loop or if you wire an empty array to the For Loop as an input with auto-indexing enabled. The loop does not execute, and any output tunnel with auto-indexing disabled contains the default value for the tunnel data type. Use shift registers to transfer values through a loop regardless of whether the loop executes.
