EMS-The Meta Mail System for CICS

In the twenty years since CASI's EMS electronic mail system was released for CICS, the core product has been enhanced and enlarged to include many functions not commonly thought of as "E-Mail" such as calendaring, text document storage, and forms processing.

META, the Greek root meaning "transformed, or transcending" indicates what EMS has evolved into: a comprehensive suite of electronic mail, personal productivity, and application-development tools. These added functions have become enablers for a new class of applications that can be developed by users without formal training as programmers. We refer to them as "mail-enabled applications."
