VI compatibility with older LabVIEW versions

[PunkFloyd]

I am using LabVIEW 8 to implement some VIs that will allow one to use one of our data acquisition devices. My question is, will these VIs be able to be used by older versions of LabVIEW? I'm not using anything fancy that doesn't exist on earlier versions; my VIs are mainly just simple wrappers around CIN calls.

As a minimum I need these VIs to run on version 6. Is this possible, or am I going to have to break down and re-implmement my VIs on an older version? I am aware of the "Save for previous version" option, but that only goes back one version (7.1 in my case).

Thanks in advance.

Newer vi's can't be run by older versions of LabVIEW. As you have noted LabVIEW 8 can save vi's that don't use LV 8 specific features to 7.1. Version 7.1 could save back to 7.0, etc. While you may not have any incompatible features in your vi's, they will be incompatible from the point of view that they are written in the newer version. If the vi's are developed in the earlier version they usually can be loaded by the the new version (I loaded a LabVIEW 5.1 vi today in 7.1, it complained about some things that had changed such as coercion of values, but otherwise loaded and compiled.)

P.M.

That's what I was afraid of. Thanks for taking the time to reply.

HI MD
why don't you make an application ?

If you don't want to rebuild the code in an earlier version, you can try posting the VIs here in the 7.1 format and ask that someone back-save it as far as you need. People with 6.1, 7.0 and 7.1 should be able to do that for you.
