Hi Binyamin and Seymour Thanks for your advices. "Is the 0C4 in your code or did you possibly mess up other storage?" According to IPCS the 0C4 is in my code, failing instruction is when I store stuffs in the IEFU86 workarea (only when a new user login or logout).
"I would advise testing the length of the work area against your required length." The IEFU86 WorkArea length is 1024 (SMXP_WORKAREA_LENGTH in SYS1.MACLIB(IFAEXITP) and x'400' when I dumped it), I only use few bytes. But, my original question was, is the IEFU86 workarea shared and if yes, do you use it to safely store stuffs inside ? Or this workarea is not to be used to store stuffs and has another utility ? Thank you
