Change a code from version 8 to 7

I created a code which works with V8, but a client will stay on V7. So I have to modify it back to V7. What to consider?

- Can I open the ODCL (from 8) with 7? Or will it work with "save as LSP"?
- Are the underscores the only thing to change?
- ....

Unfortunately the only way to go back is to recreate the odcl project from scratch. The lisp can be modified pretty easily as you surmise. Maybe you can find a bigger hammer to get the client to install V8?

Thanks Owen

I will see.
