Rascal Systems Inc, Norcross, Georgia, has launched an object-oriented applications development tool called Rascal, for Unix, Xenix, AIX, MS-DOS and VMS. Rascal represents application components like menus, data entry forms, reports and database cross-references as object classes, and stores in an object database, from where they are retrieved at run-time. Higher-level objects can be created by combining lower-level objects. Rascal costs $2,000 for a Unix development version supporting up to eight users, plus a $400 run-time fee for one processor – the fee falls as more CPUs are added. A system for nine users or more is $3,000 with run-time fee starting at $700.
