Note: This function does not really reactivate the system console. That can only be done by the operating system. What this function does is make the inactive system console an active EMCS console that the operating system thinks is a system console. By disallowing the MCSOPER programming interface from making an inactive system console active, IBM is protecting the name of the system console from being used as an EMCS console. Since most installations have their system console name defined in their CONSOLxx parmlib member, this will ensure that the reIPLing of the system is successful in making the system console active again with the desired name. If you reuse the name to activate an EMCS console prior to reIPLing, a system console will be active but it will have a different name. Note: If you do not want the console name to be associated with the system console anymore, you can remove its console definition via IEARELEC. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
