The only that I can think of is to load the table at IPL time (CLPA) and thus not require a user written program to allocate the HVCOMMON and load it. Also, the LPA loading could resolve any ADCONS in the module. This latter could be done if IBM were to allow a "directed LOAD" into HVCOMMON by a program. Otherwise some other method for "pointers" would need to be done. Either the loading program would need to resolve them, or the loaded pointers would need to be "offsets" from the base address of the HVCOMMON area and resolved each time they were used at execution time. Anybody who tried actually running such code would get just what the deserve. Derisive laughter from others. Just my thoughts. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
