This article describes a program which tracks the acquiring and releasing of virtual storage in the IBM Virtual Machine/System Product: Conversational Monitor System (CMS). Upon request, the program will generate a list of virtual storage spaces that were acquired but not released as of the time of the request. CMS allows applications to request and release storage using the DMSFREE and DMSFRET macros. The application that requests the storage does not necessarily have to be the one that releases the storage. Occasionally, applications exist that acquire storage, but the storage is never released. In such instances, the storage remains reserved until the user either logs off or reinitializes his/her CMS session.
