Are there any restrictions imposed by the CCF Compiler that Pronto Edit does not enforce? I won't go into the details of how I got to this point, but here's the situation. I successfully used the Decompiler on my CCF. At least I think it was successful. The decompiler didn't complain and a brief look at the CSF didn't reveal any obvious problems. When I tried to compile the CSF I got an error - Error E0017 : "Invalid Device Panel". The problem is the panel it's complaining about does exist, Pronto Edit has no problem with it, and the whole CCF works just fine.

I'm very confused by the whole thing. Does anyone know what might be going wrong?

I ran into one, I had multiple devices with the same name. I got the same message. In my case I could just change the device name (without affecting anything) and it worked. I used upper case for one name and lower case for the other. (I had multiple TAPE devices)

Thanks, that's probably it. I have quite a few devices that share the same name.
