Problem conclusion
*************************************************************** * FUNCTION AFFECTED: LANGUAGE ENVIRONMENT (PH66872)* * High Level Assembler * *************************************************************** * DESCRIPTION : Other * *************************************************************** * TIMING : Post-APPLY * *************************************************************** This APAR includes a new version of the standard installation defaults module ASMADOPT and the macro ASMAOPT used to build it. If the default options module has been customized, for example using USERMOD ML00001 as defined in the sample ASMAOPTS job, then the customization needs to be reapplied after installing this update in order to avoid reverting to standard defaults. The new instruction table Z17 (with alternative name ZSB) is updated to remove unsupported instructions.
