Summary
roo!™ is a new object-oriented programming language, that is characterized by the simplicity and dynamism of Classic Rexx. The language includes the usual object-oriented suspects -- abstraction, information hiding, class inheritance and derivation, method overriding, and polymorphism. Many NetRexx innovations are included. A variety of commonly used classes are built-in within the language's execution environment. Classic Rexx programs can be executed directly, without modification. In addition, a roo!™ dynamic link library (DLL) is provided, which enables cooperative processing with programs written in C/C++ or Java programming languages.

Language Objectives

Provide object-oriented capabilities

    encapsulation

    abstraction

    derivation

    polymorphism


Ability to interpret Classic Rexx programs without modification.

    all Classic Rexx instructions and built-in functions

    arbitrary precision decimal arithmetic -- big numbers

    internal and external procedures

    compound stems/symbols

    call on/signal on condition handlers


Minimal Rexx language extensions

    class, method instructions

    class variables -- local, shared, static

    ^, ^^, and ~ operators

    new objection condition type, which can be programatically raised

    Instance option of datatype built-in function

    ! special command recognition

    { } shorthand vector expression

    built-in classes


Some NetRexx innovations

    [ ] array-like operators

    catch, finally condition handlers

    loop over aggregate objects, and compound stem groups

roo!™ is accompanied by Revu™, which is a colorful text file viewing accessory. The following is an extract of the msgbox.roo example program, as displayed by Revu™.

Revu™ is also used as a presentation tool by the roo!™ interactive trace facility.
