ORCA/C is a complete C language development system for the Apple IIGS computer. You get all the software you need to write top quality programs in C. ORCA/C includes an ANSI compliant C compiler, most ANSI C libraries and several UNIX and Apple-specific libraries. You also get a linker, samples, and both a desktop development environment and a UNIX-like text development environment. You even get Rez, Apple's resource compiler, absolutely free!

Using ORCA/C, you can easily write any kind of Apple IIGS program. It's easy to write the text programs you find in programming books or desktop programs with menus and windows. You can even write classic desk accessories, new desk accessories, inits, control panel devices, HyperCard XCMDs or HyperStudio NBAs.

A separate samples disk, included free with ORCA/C, is filled with programming examples and complete source code. The samples show CDAs, NDAs, XCMDs, NBAs, desktop programs, graphics programs and text based programs. Also included is a commercial quality Reversi game which will answer many of your questions concerning the intricacies of using the Apple IIGS toolbox.

As an ORCA language, ORCA/C also works smoothly with all ORCA and APW compatible languages. You can add Pascal, assembly language, Modula-2 or Integer BASIC, and all of the languages will work smoothly together. Whether you want to write a single program using several languages, or use different languages without switching programming environments, you'll find the ORCA languages will do the job.

Here are just some of the major features you'll find in ORCA/C:
