The LXRES and ETCRE services build control blocks in the PCAUTH private area.
All of the definitions you specify in your ETDEF statements get translated into "ETE" control blocks inside PCAUTH LSQA . The LXAT is the table of linkage index allocations (see Data Areas manual) and is in PCAUTH private (sp229). Without the LX there is no way for the ETEs to be accessed to build the PC routine invocation for client callers as the first stage lookup in the LXAT will fail. This applies for both PC-cp and PC-ss. It is also worth remembering that the only difference between a PC-cp and PC-ss in the ETE is the SSWITCH=YES/NO option on ETDEF - (obviously the coding techniques for the actual PC routine will most likely be different to cater for the entry environment). I imagine that there is a RESMGR routine that is established for the calling task/ASID when LXRES is invoked so that LXAT cleanup actions can be performed when the LXRES-issuing TCB terminates and has not cleaned up properly using LXFRE etc. Rob Scott Lead Developer Rocket Software 77 Fourth Avenue .

I agree with both of You. I wrestling with the statement in Extended Addressability. It specifically identifies entry tables PCss *AND* not PCcp. I interpret that as entry tables describing PCcp routines are allowed in a seperate step. Sorry for being so dense, but thats how I intrepret it. Yes LX are destroted at Task Termination. And the Extended Addressability specifically states PCss, thats what is odd. It does not say All Entry Tables...
