what is the best way to handle input parameter

[Senior_Technical_Rep]

When writing sub-vi's, what is the best way to handle input parameter range checking? On the front panel I can choose to have numeric values coerced to be within range, but this does not affect constants or controls wired to the vi when used as a sub-vi. I can build range checking into the vi, but this can result in a cluttered looking vi. Do you have any suggestions.

As you discovered, the Range and Coercion properties of controls do not work when used in sub-vis.

Your best option is to go ahead and build your range checking into your sub-vis. If it�s something you will be doing a lot, just make your range checking a sub-vi and drop it where needed. This will keep the clutter to a minimum. You may end up with more than one range checking VI if you need different functionality, but this will still make less clutter and easier re-use.
