An Introduction to Clascal Susan Keohan nacintoshUser Education Apple Co.puter, Inc. Preface This is a conceptual introduction to ClascaL not a reference manual. Example programs and syntax diagrams follow the text. The purpose of this document is to introduce experienced Pascal programmers to the concepts necessary to make the transition from a traditional procedure-oriented environment to Clascal's . object-oriented environment. This document assumes you are familiar with Lisa Pascal and QuickDraw. All programs and program fragments are boldface in this document. for example, thisShape.Erase is a program fragment. Table of Contents Introduction ...... . Comparing Pascal and Clascal Pascal.

J./~ AI7 InlrDtb:fion to CI6SC61 "1y198*, An Introduction to Clascal Introduction ellsoll is I set of extensions to Lisl Pasoal that adds objects and classes of objects to the language. The sesaantic extensions of elascal were inspired by the language s.Blltalk 76. The syntactic extensions were influenced by the language SillJII 67.. It is not necessary to know s.alltalk or Simula before learning elascal. elascal differs little fro. Pascal syntactically. The ..jor difference between the languages is in progr_ing technique. bn you write a Pascal proor., your procedure and fooction specifications are separate fro. your data structure specifications. When a Pasoal proor. is rCA data is passed to a procedure or function, and the procedure or function acts on the data. In elascal the data structures of an object and its procedures and functions'ar~ specified together 1n a class declaration. Ihen the program is rWl, objects are created. These objects use the functions and procedures that the program.er specified when defining the data structure. All the operations that an object eM perf0111 are defined by the object's class. As a result, progr.. modularity is i~roYed. In Pascal, to add new variations to an old data type, you ..st either define new types inc~atible rith the old type, or. edit existing code to add new cases to a variant record type and to procedures that act on that type. In ClasoaL you can define subclasses of existing classes without editing existing code Met without introducing incDq)atible types. As a result, progr_ extensibility is illproved. CCJIIparing Pasc.l and Clascal Clascal is a superset of Lisa Pascal. Because the readers of this doc\IIent are Pascal progr...ers, CI.scal oonoepts are CGIIPIred to Pascal concepts throughout. this doouIent. As a Pascal progrlllller, you should have little difficulty adjusting to ClesoaL because III)St of w…

I ~' - --~-" To: Bob-Bailey Gary Butts - APG Dave Christensen - APG Mike Clark - - APG Burrell Smith From: Peter Ashkin Subj: Front Desk Bus - An Alternative Proposal Date: August 20, 1984 To make the "Front Desk Bus" a more fleiible and powerful interface, I believe that it should have the following properties: The bus shall be bidirectional. [An input only bus is too 1. restrictive.) 2. Each device on the bus has a unique address. For practical purposed the address range should be 0 - 15. Some of these addresses may be reserved for broadcasting universal messages. (This seems like a sane number of devices, particularly since there eiists today only three devices; keyboard, keypad and mouse.) 3. . All messages on the bus shall be filed length. (This facilitates the decoding of commands by devices of limited intelligence.) 4. Only one rdevice at a time can be "bus master". This ability can be relinquished, and another device can assume bus mastership. (Usually the host will be the bus master, but the interface should not preclude a future device which may master the bus. Also, by having an undisputed bus master, there are no bus contention problems.) 5. There shall be a limited number of commands. Commands should be broken into two groups, basic commands (T AL~ and LISTBN) which all devices on the bus shall understand; and advanced commands which only intelligent devices (as appropriate) should understand. (This makes the command interpreter, be it hardware or software, simple. It also allows more comple1 devices to used some of the "fancier" teatures of the bus.) There shall be only one active talker on the bus at any time, this may be the host or a remote device. (When a new device is commanded to T ALl, an old device that was addressed to T ALl is "untalked".) 6. FrontJ&s_k_B_u_s__ ~,-- __ _ Auaus.t 24. J 984 7. Bus must accept devices that talk at different speeds. The host, -at-a· minimum, must be able to listen at various speeds. (This implies that the data on the bus must be se1f-clocked... By not rigidly filing the speed of transmission, the bus does not need to be crystal (etc.) controlled.] 11 8. There can be multiple active listeners on the bus. (Listen commands are additive, as needed, multiple devices can be addressed to listen. To remove a selected listener, a special Unlisten" command is sent to globally deselect all listeners.) 11 9. An interrupt mechanism must be available which circumvents the needs to poll devices that need service. (Since the bus is relatively slow, the interrupt latency time in a polled environment is long. The ability to interrupt the master for service is important.) 10. There shall eiist a mechanism that sends a unique message that puts all devices on the bus into the command (reset) mode. (This is important if for some reason the bus gets hung".) 11 11. There should be a minimum number of "time-outs" needed on the bus. The only needed time out should be to time out a non-responsi…

Assembly-Language Development Assembly-language programmers cannot simply re-compile for PowerPC; some sort of porting will be required Our recommendation is that you re-write your assembly code as portable C source code. While many assembly language programmers feel that this is a poor chOice, the design of the PowerPC Macintosh removes many of the reasons that developers write in assembly language. The 4 major reasons developers write in assembly language are 1) speed, 2) linking different calling conventions together, 3) addressing custom hardware installed in a particular machine, or 4) a need to jump to a particular routine instead of using a subroutine call. We'll look at how the PowerPC programming model addresses each of these issues. Migration Strategies for PowerPC Page 1 • The first case, speed, should be handled adequately by the optimizing Ccompilers. Creating optimized code for the PowerPC is no easy feat, and it is easy to overlook one rule or another wh…
