This history was written so that this rather interesting bit of computer technology would be recorded for those with an interest in technical histories like this. The author has never worked for Apple Computer, but has been involved with software development for Apple's many computers since 1978 and has extensively used all of Apple's Pascal implementations. As such, the facts contained herein are based upon personal memories and Apple technical documents and may be inaccurate. The author hopes that those in the know about Apple's Pascal work will correct and extend upon this paper so that the history of Apple's Pascals will be made complete.

At this time Apple's software development efforts were based upon the BASIC and 6502 assembly languages. The key players in bringing Pascal to the Apple ][ were Bill Atkinson and Jef Raskin. Atkinson convinced Apple's management that the Pascal language would be much better for Apple's own software development activities than either BASIC or 6502 assembly. Atkinson and Raskin licensed the Pascal language and development system from the University of California at San Diego (UCSD) and began an internal Pascal development group. Apple's ][ Pascal system included a Pascal compiler, modal editor, 6502 assembler, a powerful filer, and several utility programs (e.g. program segment mapper). The system was controlled via a command line user interface. The Apple ][ Pascal compiled to P-Code which was based upon byte codes and a stack architecture. This P-Code was interpreted by an interpreter written in 6502 assembly. 6502 assembly language routines could also be linked with P-Code programs. Identifiers in ][ Pascal were recognized only up to 8 characters, a painful limitation which Apple did not remove until its Macintosh MPW Pascal. Pascal's memory use was restricted to 64k bytes due t…

Insert the female boot in drive #5: and power up the Lisa. The female boot volume can also reside on a hard disk. SYSTEM.STARTUP on the male boot volume automatically executes MONBOOT, the program that starts up the Monitor on the Lisa. If you type space during the boot process, MONBOOT is not executed. If you type 'D' during the boot process, the debugging version of the Monitor is booted. Page 1 16-Feb-82 The Pascal Development System Manual The Moni tor comes up on the Lisa scret!n. If you want it to appear on the Apple II monitor or the Soroc (~onnected to the UART port, change the MON.STARTUP program as follows: 1) for the Apple window: remo",e MON.

This release includes the Pascal compiler which supports Classses • . This release also includes numerous bug fixes. The loader has been enhanced to implement code remembering. The Monitor has been enhanced to remember directories. The user should notice a 2x to 4x improvement in ~ystem through put (ie. typical process launch is qui te short). This release provides a viable Twiggy based development system. Installa.t~on This release consists of a complete development system contained on a Single Twiggy. Simply COpy the contents of the Twiggy onto your root volume (ie. #5: of the worKing device) and reboot wi th the new boot disk. The files listed below in the section cal led Boot Fi les do not need to be copied to your root volume. The pr-ocess above assumes that your root volume is named LISA:.

Se~ attached erro~ message 1 isting. b) Th~ assembler does not recognize- the-- directive .ABSOLUTE anymore. ar~ using it in your source files, comment- it out. c) The prompt line has- been changed for option input. options, do the following: input file: options: options: input file: So if you If you want to enter <enter ?) <enter your options - e-.g. +c) <enter return to terminate options entry) <enter your file name) and continue as you always do. 1fat· any time in the promp t stage, you dec i de you rea 11 y do not wan t to assemble, just hit the. (CLEAR) Key on th~ Key pad and you can escape from the assembler cleanly. d) There is. a pretty 1 i·sting option in the assembler, +p. If the option is chosen, you~ 1 isting should have all the forward references patched. (But do not use the directive .NOPATCHLILST if you want all forward references to be patched.) e) Macro processing has been improved. You can turn macro expansion listing on or off us i n9 d i rec t i ves- HACROLI ST and NCt1ACROLIST anyt ime in your program. f) For the Diagnostics Group, the .CODE file option has been restored. Do not be alarmed when you do a verify on the new and old .CODE files and find them do not compare. The .CODE file generated by this assembler should be in correct format for the DHT loader. LISA N68K assembler error message listing: 1 undefined label operand out of range must have procedure name number of parameters expected extra garbage on line input line over 80 characters not enough .IF's Illegal use of .REF label identifier 'previously declared 10 improper format 11 .EQU expected 12 must .EQU before use if not to a label 13 macro identifier expected 14 word addressed machine 15 bacKward .ORG currently not allowed 16 identifier expected 17 constant expected 18 inval id structure 19 extra special symbol 20 branch too fa~ 21 variable not PC relative 22 unexpected .ENDN 23 not enough macro parameters 24 operand not absolut~ 2S illegal use of special symbols 26 ill-formed expression 27 not enough operands 28 cannot handle this relative expression 29 constant overfl~ 30 illegal decimal constant 31 illegal octal constant 32 illegal binary constant 33 inval id key word 34· macro stack overf low - 5 nes ted lim it 35 includ~ files may not b~ nested 36 unexpected end of input 37 this is a bad place for an .INCLUDE file 38 anI y 1abel s & c.omments may occuPY col 1 39 expected local label 40 1oca 1 1abe 1 st acK overf low. 41 string constant must be on one line 42 string constant exceeds 80 characters 43 illegal use of macro parameter 44 Illegal use of .DEF label 45 expected key word 46 string expected 47 nested macro definitions illegal 48 '=' or '()' expected 49 may not EQU to undefined labels 50 Not eve…

Date: August 23, 1982 To: Lisa Software, lisa Users From: Ken Friedenbach Subject: Release 10.2 of the '~~§.f4~(,Development S~~t:~m --.-------.-----.------------~'-,~~~...,-~,-~~'-:~~..;~--.....-'--~".... -------..,.~.--~~-------~-----~ Overview '(": This release is intended for Lisa users who W;q.llt; to use~hthe Development '.'.". . System on O.S. 5.2.3 (or later). There are also ~[p~mber of bugs that have been fixed in the:10.0 release. It is strongly recp~ended that you go to 10.2 on the Monitor at the same time you install 10~2 on O.S. 5.2.x. CAUTION: Beginning with this release, INTRINSIC.LIB can no longer be moved freely fronf the Moni tor to the O. This is ~::because the Development System contains some Intrinsic Units (in·*OBJIOLIB.OBJ on the Monitor and in OBJIOLIB.OBJ on the O.S.). s.. CAUTION: The O.S. release contains·files of "the same name as the Monitor release, but they are not the same files. (They were· linked against different PasLib files and there are compile time conditional compilation statements.) This will be remedied in a future release when we plan to have one Pas Lib and support for run-time conditionals. Major Changes: 1. Several Compiler/Code Generator bugs were fixed: a. P:= pointer (ord (Q) + expr); now generates correct code when expr contains P as a subexpression. Thanks to Brad Silverberg for an excellent bug report and some diagnostic support. Thanks to Rich Page for help with the fix. b. The Code Generator had a limit of 100 different External References per procedure which was not being checked. This limit has now been extended to 200 and a new Compiler Error message is generated when the limit is exceeded: 309 Too many external references. (note this in your Manual) Thanks to Chris Moeller for a good .bug report and example. c. The code generator had a bug in the computation of block numbers for large Units (greater than 64 blocks). The bug resulted in negative block numbers, which apparently worked OK on the Monitor. (Unit I/O must mask the sign bit). The bug was uncovered when FileIO began doing more I/O checking. Thanks to Chris Franklin for the bug report and example. 2J.-Aug-82 - 2 - PASCAL Development System (10.2) 2. An error in the 10.0 IUManager caused Lisa to reset whenever a new Unit or Segment was added to Intrinsic.lib. This has been fixed. Thanks to Lorraine Daniels for the bug report. 3. PackSeg now supports a single Pack Table for the O.S. PackSeg will ask an additional question about reading a table. If the response is positive, PackSeg prompts for a filename with the default being *PACKTABLE.LIB. If the response is negative, a unique table is built (as before). 4. DumpHex has had a bug fixed related to closing files which were not opened. 5. The Compiler, Code Generator, and IULinker make use of Rick Meyers Hardware drivers to report Elapsed Time. The time is measured from the beginning of execution to just before exit. Hence, the only repeatable times are …
