My unmade point: GCS was cloned from CMS as it existed in VM/SP 3. Additional code added to tighten file system security, support cross-virtual machine multitasking and to run applications in problem state is VM-written code. We did not import code from OS/360 MFT. I know this: I was there, writing the code for the GCS recovery machine, as well as working on DEB security in the OS simulation for READ, WRITE, POINT, GET, and PUT. Where the existing CMS MVS/SP (at the time) simulation was not sufficient to meet VTAM's and NetView's requirements, the GCS versions of those interfaces were updated with extra function.
