I have a llb created in LabVIEW 4.1. Now my company have buied LabVIEW 8.2. I have tried to convert this llb from 4.1 to 8.2, but main vi have "broken" arrow and the message is
CIN refered from this vi uses an external subroutine. External subroutine are no longer supported in this version of LabVIEW.
Unfortunately, with upgrades, some support of "stuff" is lost along the way, and you've hit one. If you have access to the source code your best bet is to convert it to a DLL. You can also try the suggestions in this post and in the "Using External Code in LabVIEW" manual that should have been installed with LabVIEW.
