MANTIS
A structured, full-function procedural 4GL and application development system from Cincom. MANTIS enables the developer to design prototypes, create transaction screens and reports, define logical data views, write structured procedures, and dynamically test, correct, document, secure, and release applications for production in a single, integrated, interactive session.
MANTIS applications can be enhanced with gOOi, the graphical object-oriented interface, which creates graphical Windows representations of existing MANTIS screens.
