 I have compiled a project with a project ID of greater than 500, and am getting a compilation error:
Error: Invalid Project ID - must be between 1 and 500

When I look at the help files on this topic valid project IDs fall between 1 - 1022. Which is correct?

 Project IDs of greater than 500 have been found to be at risk of memory corruption in the runtime environment. Thus, the compiler will now search and flag this as a compile error.

In order to fix this compile error, change the project ID to one which is less than 500. This can be done by editing the Project ID field of Project Properties.
