Memory protection this, memory protection that. Simply read_protecting LoadSeg'ged CODE segments would be quite a boost. Likewise, read & write protecting all memory on the freelist would be a big help. Of course, performing the latter would probably run out of memory segment descriptors mighty fast unless AllocMem() was rewritten. Sure, apps could still wildly trash system-common data structures like ExecBase, but it would be a big step forward in preventing tasks from corrupting other tasks & free memory. -djh +----------------------------------------------------------------------------+ | Dallas J.
