If a program manually adds :>subsystem control blocks to the end of the SSCT chain, hash table :>lookups for that subsystem will fail and require fall-back to sequential :>lookup resulting in longer path lengths. The HASH index contained a pointer to the last subsystem in the hash table. If a directed SSOB was issued, the hash chain was first searched, and if not found a sequential search was done from the last pre-defined subsystem. The entire sequence was never searched for a directed SSOB (AFAIR). -- Binyamin Dissen <bdis...@dissensoftware.com> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
