All of the Ethernets currently within PARC are of the earlier, 3 MBits/sec variety.l6496d2999e12jk40\bg8B282b7B38b8B29b8B35f1 336f0 Executive.run A distinguished Alto subsystem that provides simple commands to inspect and manipulate the file system directory, and to initiate other subsystems.l6496d2999e12jk40\bg13B22b9B file extension The portion of a file name that appears following a period (possibly null).

Groups can also be used for other purposes, such as access control. The R-names that constitute a group are called its members. In addition, a group has friends and owners: a friend is someone who may add or delete herself from the group, while an owner may add or delete anyone from the group.l6496d2999e12jk40\bg5B19b10B55b5B6b17B31b5B18b3B52b5B94b5B16i10I15b5B5i8I4i9I3i6I51b5B11i5I35b6B Guibas A unit of complexity of mathematical arguments, defined to be Leo's maximum sustainable hair-level.

A Dorado has five partitions, while a Dolphin has two. Partitions are numbered starting at 1; the phrase ``partition 0'' refers to the current default partition. The current partition is use is determined by the contents of some registers that belong to the disk microcode. You can change these registers with the ``partition.~'' command available in the Executive and in the NetExec. A (14-sector) partition has 22,736 Alto pages (11.6 MBtyes). It took a little adroit shoehorning to fit two full partitions onto a Dolphin's disk: it turns out that a Shugart 4000 has just one too few cylinders to squeeze in two full partitions. So we have to ask the heads to seek off the end of the advertised disk (on the inside, it happens), and put one more cylinder in there! Ah, the joys of hardware hacking...l6496d2999e12jk40\bg9B94b4B1b2B12b6B10b10B10b7B11b10B111b9B206f1 12f0b9B17b4B18f1 358f0 PasMesa A program that more or less compiles Pascal source into Mesa source, and hence assists in importing Pascal programs into our environment; developed in CSL. l6496d2999e12jk40\bg7B57b4B92b4B path name A complete description of a directory or subdirectory on which files may be storedeverything you need to know to get the file except the file name.

The 8000 architecture was created in CSL.l6496d2999e12jk40\bg4B4b4B35b4B102b4B52b4B Stinger A Hornet located in ISL, running Press.l6496d2999e12jk40\bg7B3b6B12b3B10b5B subdirectory File directories on an IFS can be divided into a hierarchical collection of subdirectories. The subdirectory names are listed from the top of the tree down to the bottom, and are separated by the single character ">". For example, the directory [Ivy] has a subdirectory called MakeConfig on which files related to the MakeConfig program or stored. To refer to the file MakeConfig.Press on this subdirectory, one would write: [Ivy]MakeConfig>MakeConfig.Pressl6496d2999e12jk40\bg12B24b3B221b15B27b10B31b10B41b1B subsystem A program running under a specific operating system. Normally used to refer to Alto programs that run under the Alto OS, but also used to refer to PDP-10 programs that run under TENEX.l6496d2999e12jk40\bg9B119b2B59b5B Swat A debugger used primarily for BCPL programs. Also, the key used in conjunction with the "control" and "shift" keys to invoke the debugger. Used as a verb to refer to the act of striking these keys or entering the debugger.l6496d2999e12jk40\bg4B31b4B Swatee A file used by debugging programs (both Swat and the Mesa debugger) to hold the core image of the program being debugged. Also used as a scratch file by many Alto subsystems. Not to be deleted under any circumstances.l6496d2999e12jk40\bg6B41b4B Sys.boot An Alto disk file containing the executable representation of the Alto Operating System.l6496d2999e12jk40\bg8B SysDir. The Alto file directory. Roughly speaking, this file contains the mapping from file names to starting disk locations.l6496d2999e12jk40\bg7B SysFont.al An Alto screen font used by the Executive and (generally) as a default by other programs. The safest way to change your SysFont is with the Delete.~ and Copy.~ commands of the Alto Executive. Simply FTP'ing a new font on top of SysFont will cause exotic behavior during the CounterJunta when FTP is finished. l6496d2999e12jk40\bg10B33b9B50f1 220f0 system modelling A part of the Cedar project, aiming at giving programmers help is describing the structure of large systems: getting all the versions correct and the like.l6496d2999e12jk40\bg16B15b5B Systems Center Half of PARC; the other half is the Science Center. The rationale behind the specifics of the division are unclear.l6496d2999e12jk40\bg14B38b14B Tajo An environment for developing Mesa programs that exists in both Alto and Pilot versions; this environment comes complete with a consistent philosophy about many things, including how screen space should be used, which window should be listening to the keyboard at any given moment, and much more. Each facility in the Tajo environment is called a Tool, and Tajo itself was once called the Tools Environment.l6496d2999e12jk40\bg4B31b4B30b4B5b5B242b5B24b4B6b4B28b18B Telnet A PUP-based protocol used to establish full-duplex, teletype-like communication with a remote computer. (The term is borrowed from a similar protocol used on the Arpa network.) Chat speaks this protocol.l6496d2999e12jk40\bg6B3b3B174b4B Tenex An operating system for the DEC PDP-10 computer, which also runs on MAXC.l6496d2999e12jk40\bg5B69b4B TEX A document compiler written by Don Knuth at Stanford; there are two implementations of TEX at PARC, one in Sail that runs on Maxc, the other in Mesa for D-machines. TEX can handle mathematical formulas, but doesn't let you see anything like what you get.l6496d2999e12jk40\bg3B89b3B4b4B27b4B15b4B5b11B2b3B thumbing A technique of positioning a file (usually text) to an arbitrary position, usually for viewing on a display.l6496d2999e12jk40\bg8B Tioga A project in ISL to build an integrated editor/typesetter in Mesa.l6496d2999e12jk40\bg5B14b3B45b4B Tool A facility available in the Tajo environment, or the program that makes that facility available. For example, one speaks of the ``File Tool'', which can perform file transfers for you.l6496d2999e12jk40\bg4B29b4B Tools Environment Former name for Tajo.l6496d2999e12jk40\bg17B17b5B transaction A collection of reads and writes of shared data that is guaranteed to be atomic: either all of the writes happen (the transaction commits) or none of them do (it aborts). Furthermore, the reads will see consistent data in that either all of the writes made by some other transaction will be visible, or none of them will.l6496d2999e12jk40\bg11B120b12Bi7I25i6I104b11B typescript An Alto file used to back-up information (usually text) appearing in a region of the display.l6496d2999e12jk40\bg10B Twinkle A Gateway in Building 35 of PARC.l6496d2999e12jk40\bg7B3b7B4b11B4b4B Universal File System At the moment, merely a dream: in particular, the dream that someday all of our files will live in a common system, implemented in a distributed and reliable fashion by remote servers, for which all local disks will merely be automatically-managed caches. There is some hope that this dream will be turned into reality someday by something to be built on top of Cedar and Alpine.l6496d2999e12jk40\bg21B367b5B5b7B user A person (rather than a program) who avails herself of the services of some program or system. At the moment, the author is a user of Bravo. See client.l6496d2999e12jk40\bg4B128b4B4b5B7b7B user.cm A file containing a number of logically distinct sections that each define certain configuration parameters (e.g., the location of a preferred printer server for a particular file format). Programs that interpret such parameters are often organized to read user.cm only at installation time (e.g., Bravo).l6496d2999e12jk40\bg7B144b14B117b7B18b5B WaterLily A Mesa program that does source compares: compares two text files and reports the differences. Available in both Alto/Mesa and PreCascade.l6496d2999e12jk40\bg9B3b4B114b4B5b10B window A display region, usually rectangular, used to view (a portion of) an image that generally exceeds the bounds of the region.l6496d2999e12jk40\bg6B Wonder A Dover on the third floor of Building 35.l6496d2999e12jk40\bg6B3b5B23b12B world-swap The process of writing out the complete state of a machine's processer and memory onto a disk file, and of swapping in a different state. Most of the debuggers in our current environment work by means of world-swaps, which swap between the debugger and the program being debugged. Note that, the more memory you have, the slower a world-swap will be.l6496d2999e12jk40\bg10B206b10B68f1 69f0 XBS Acronym for Xerox Business Systems; a former organization, XBS was subsumed by OPD. l6496d2999e12jk40\bg3B13u1U5u1U8u1U32b3B17b4B XEOS An IFS located at EOS.l6496d2999e12jk40\bg4B4b3B12b3B XGP Acronym for Xerox Graphics Printer.
