Hi, not being a PASE expert here, but with some help from other folks, we can state that while the current RDi tools do not officially support the PASE environment, if your source is in the IFS you can use the RDi product and the RSE to browse the file system. If you double click on a source file, it'll open inside RDi and the base C/C++ functionality will start.
We have not implemented support to understand output from builds, so there is no error feedback and we have not provided a debugger for the PASE environment.
Do you have a business case for these tools? If so please contact me privately through my email address and we can see how we can improve support.
