Such a task will be limited to 2 APRs (5 & 6), while APRs 0-4 are mapped to the kernel and APR 7 is the I/O page. Another way is to switch to kernel mode in the task using SWST$. For this, you still need to build the task privileged, but you can build it without getting the limited address space mentioned above. A third is to create a common region which is the I/O page, and then task build against that common region, or else create a window to that region at runtime, using CRRG$ and MAP$. The common region way is documented in some manual, but I don't remember offhand which one. Johnny
