ORCA/Pascal is a complete Pascal language development system for the Apple IIGS computer. You get all the software you need to write top quality programs in Pascal. ORCA/Pascal includes an ISO compliant Pascal compiler with many extensions, including Apple's Object Pascal language extensions. You also get a linker, libraries, 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/Pascal, 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/Pascal, 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/Pascal also works smoothly with all ORCA and APW compatible languages. You can add C, 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/Pascal:

Compiler Features

• ISO Standard Pascal Compiler, with extensions.
• Supports Apple's Object Pascal extensions.
• Full access to the Apple IIGS toolbox.
• Powerful directives control the memory model (large or small), optimizations, and turn off extensions to the ISO Pascal standard.
• Full trace back of run time errors shows where errors occurred, and what was called to get there.
• Sets can have up to 2048 elements.
• UCSD-style strings, plus ISO Pascal strings up to 32767 characters long.
• Double precision real, long integers, and byte length integers.
• You can define and access your own libraries.
• UCSD-style units for separate compilation.
• Partial compilation is supported for fast turnaround, giving effective compiler speeds in excess of 10,000 lines per minute on an unaccelerated Apple IIGS.
• Turn run time checks on for unsurpassed error checking, or off for faster execution.
• Bit manipulation operators (and, or, exclusive or, bit shifting, and one's compliment) help you write efficient systems programs.
• 'Otherwise' on case statements.
• Pointer arithmetic and typeless pointers.
• Convert numbers to strings and strings to numbers.
• Type casting.
• Extensions for scientific programming (exponentiation, more trigonometric primitives and random number generation).

Source Level Debugger

• Debug desktop or text programs.
• Step, trace and full speed execution.
• Execute to the end of a subroutine.
• Step through a subroutine.
• Set/clear break points.
• Watch variables change values.
• Profiler helps you find out where your program is spending time.

The Desktop Development Environment

• Pull down menus.
• Mouse based commands with keystroke equivalents.
• Multiple windows - the number is limited only by memory.
• File size limited only by available memory.
• Text and graphics windows displayed at the same time.
• Run desktop programs without leaving the environment.
• Cut, copy, paste, undo and split screen.
• Copy or delete files, initialize disks.
• Shell commands accessible from the desktop.

The Text Development Environment

• Full screen text editor that edits up to 10 files, with file lengths limited only by available memory.
• Powerful command driven shell works like UNIX, but uses familiar Applesoft command names.
• Supports I/O redirection and pipes.
• A fully scriptable shell lets you write shell programs for repetitive tasks.
• Online help lists commands and tells you how to use each one.
• Expandable - add our Utility Pack #1 or write your own shell utilities.
