I have never truly coded a post error routine (always use CVTBRET). Consider what must be done if a POST failed, which requires determining the reasons why the POST failed. In the vast majority of cases I would be running primary=target and will attempt a quick post first. 1. The target memory terminated Nothing to do. The RESMGR routines will clean it up. 2. The address is invalid or in the wrong key The quickpost will catch it. Also, one must consider the case which posterr will not catch, that is the storage is reallocated. Either way, the issues remains - what will you do if the post fails? -- 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.
