============================================================================= Humorous Tidbits #6: Computer Languages From The Enforcer & friends ============================================================================= Babbage - The Language of the Future Babbage is based on language elements that were discovered after the design of ADA was completed. For instance, C. A. R. Hare, in his 1980 Turing Award lecture, told of two ways of constructing a software design "One way is to make it so simple that there are obviously no deficiencies and the other way is to make it so complicated that there are no obvious deficiencies." The designers of Babbage have chosen a third alternative - a language that has only obvious deficiencies. Babbage programs are so unreliable that maintenance can begin before system integration is completed. This guarantees a steady increase in the DP job marketplace. Structured languages banned GOTOs and multiway conditional branches by replacing them with the simpler IF-THEN-ELSE structure. Babbage has a number of new conditional statements that act like termites in the structure of your program. WhatIf - Used in simulation. Branches before evaluating test ______ conditions. OrElse - Conditional threat as in : "Add these two numbers ______ OR ELSE !" WhyNot - Executes the code that follows in a devil-may-care ______ Fashion. WhoElse - Used for polling during I/O operations. _______ Elsewhere - This is where your program really is when you think _______ its here. GoingGoingGone - For writing unstructured programs. Takes a random ______________ branch to another part of your program. Does the work of 10 GOTOs. For years, programming languages have used "For", "Do Until", "Do While", etc. to mean "loop". Continuing with this trend, Babbage offers the following loop statements : Don't Do While Not - This loop is not executed if the test condition __________________ is not false (or if it's Friday afternoon) . Didn't Do - The loop executes once and hides all traces. _________ Can't Do - The looped is pooped. ________ Won't Do - The CPU halts because it doesn't like the code inside ________ the loop. Execution can be resumed by typing "May I" at the console. Might Do - Depends on how the CPU is feeling. Executed if the CPU is ________ "up", not executed if the CPU is "down", or if it feelings are hurt. Do Unto Others - Used to write the main loop for timesharing systems ______________ so that they will antagonize all users in a uniform manner. DOWAH - Used to write timing loops for computer-generated music. _____ Every self-respecting structured language has a case statement to implement multiway branching.Algol offers an indexed case statement and Pascal has a labelled case statement. Not much of a choice. Babbage offer a variety of case statements : Just-In-Case STMT - For handling afterthoughts and fudge factors. _________________ Allows you to multiply by zero to correct for accidentally dividing by zero. The Brief Case STMT - To encourage portable software. ___________________ The Open & Shut Case STMT - No proof of correctness is necessary _________________________ The In Any Case STMT - This one always works. ____________________ The Hopeless Case STMT - This one never works. ______________________ The Basket Case STMT - A really hopeless case. ____________________ The Babbage Language Design Group is continuously evaluating new features that will keep it users from reaching any level of effectiveness. For instance, Babbage's designers are now considering the Almost Equals Sign used for comparing two floating point numbers. This new feature "takes the worry out of even being close". NEW LANGUAGES COMPETE WITH APL A Usually Reliable Source Digital Equipment Corporation Somewhere in New England APL, BASIC, FORTRAN, COBOL,... these programming languages are well known and (more or less) well loved throughout the computer industry. There are numerous other languages, however, that are less well known yet still have ardent devotees. In fact, these little-known languages generally have the most fanatic admirers. For those who wish to know more about these obscure languages -- and why they are obscure -- I present the following catalog. SIMPLE SIMPLE is an acronym for Sheer Idiot's Monopurpose Programming Linguistic Environment. This language, developed at Hanover College for Technological Misfits, was designed to make it impossible to write code with errors in it. The statements are, therefore, confined to BEGIN, END, and STOP. No matter how you arrange the statements, you can't make a syntax error. Programs written in SIMPLE do nothing useful. They thus achieve the results of programs written in other languages without the tedious, frustrating process of testing and debugging. SLOBOL SLOBOL is best known for the speed, or lack of it, of its compiler. Although many compilers allow you to take a coffee break while they compile, SLOBOL compilers allow you to travel to Bolivia to pick the coffee. Forty-three programmers are known to have died of boredom sitting at their terminals while waiting for a SLOBOL program to compile. VALGOL From its modest beginnings in Southern California's San Fernando Valley, VALGOL is enjoying a dramatic surge of popularity across the industry. VALGOL commands include REALLY, LIKE, WELL, and Y*KNOW. Variables are assigned with the =LIKE and =TOTALLY operators. Other operators include the California Booleans, FERSURE and NOWAY. Repetitions of code are handled in FOR - SURE loops. Here is a sample VALGOL program: LIKE Y*KNOW (I MEAN) START IF PIZZA =LIKE BITCHEN AND B =LIKE TUBULAR AND C =LIKE GRODY**MAX THEN FOR I =LIKE 1 TO OH MAYBE 100 DO WAH - (DITTY**2) BARF(I) =TOTALLY GROSS(OUT) SURE LIKE BAG THIS PROBLEM REALLY LIKE TOTALLY(Y*KNOW) VALGOL is characterized by its unfriendly error messages. For example, when the user makes a syntax error, the interpreter displays the message: GAG ME WITH A SPOON! LAIDBACK Historically, VALGOL is a derivative of LAIDBACK, which was developed at the (now defunct) Marin County Center for T'ai Chi, Mellowness, and Computer Programming, as an alternative to the intense atmosphere in nearby Silicon Valley. The center was ideal for programmers who liked to soak in hot tubs while they worked. Unfortunately, few programmers could survive there for long, since the center outlawed pizza and RC Cola in favor of bean curd and Perrier. Many mourn the demise of LAIDBACK because of its reputation as a gentle and nonthreatening language. For example, LAIDBACK responded to syntax errors with the message: SORRY MAN, I CAN'T DEAL BEHIND THAT. SARTRE Named after the late existential philosopher, SARTRE is an extremely unstructured language. Statements in SARTRE have no purpose; they just are. Thus SARTRE programs are left to define their own functions. SARTRE programmers tend to be boring and depressed and are no fun at parties. FIFTH FIFTH is a precision mathematical language in which the data types refer to quantity. The data types range from CC, OUNCE, SHOT, and JIGGER to FIFTH (hence the name of the language), LITER, MAGNUM, and BLOTTO. Commands refer to ingredients such as CHABLIS, CHARDONNAY, CABERNET, GIN, VERMOUTH, VODKA, SCOTCH, BOURBON, CANADIAN, and WHATEVERSAROUND. The many versions of the FIFTH language reflect the sophistication and financial status of its users. Commands in the ELITE dialect include VSOP, LAFITE, and WAITER'S(RECOMMENDATION). The GUTTER dialect instead has commands for THUNDERBIRD, RIPPLE, and HOUSE(RED). The GUTTER dialect is a particular favorite of frustrated FORTH programmers who end up using this language. C- This language was named for the grade received by its creator when he submitted it as a project in a graduate programming class. C- is best described as a "low-level" programming language. In general, the langauge requires more C- statements than machine-code instructions to execute a given task. In this respect it is very similar to COBOL. LITHP This otherwise unremarkable language is distinguished by the absence of an "S" in its character set. Programmers must substitute "TH". LITHP is said to be useful in prothething lithtth. DOGO Developed at the Massachusetts Institute of Obedience Training, DOGO heralds a new era of computer-literate pets. DOGO commands include SIT, STAY, HEEL, and ROLL OVER. An innovative feature of DOGO is "puppy graphics", a small cocker spaniel that occasionally leaves deposits as he travels across the screen. Here are some thoughts from Dijkstra article "How Do We Tell Truths that Might Hurt?" in his book "Selected Writings on Computing" (Springer Verlag, 1982): FORTRAN, "the infantile disorder", by now nearly 20 years old, is hopelessly inadequate for whatever computer application you have in mind today: it is now too clumsy, too risky, and too expensive to use. PL/I --"the fatal disease"--belongs more to the problem set than to the solution set. It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope or regeneration. The use of COBOL cripples the mind; its teaching should, therefore, be regarded as a criminal offense. APL is a mistake, carried through to perfection. It is the language of the future for the programming techniques of the past:it creates a new generation of coding bums. The problems of business administration in general and database management in particular are much too difficult for people that think in IBMerese, compounded with sloppy English. About the use of language: it is impossible to sharpen a pencil with a blunt axe. It is equally vain to try to do it with ten blunt axes instead. We can found no scientific discipline, nor a healthy profession, on the technical mistakes of the Department of Defense and, mainly, one computer manufacturer. The use of anthropomorphic terminology when dealing with computing systems is a symptom of professional immaturity. In the good old days physicists repeated each other's experiments, just to be sure. Today they stick to FORTRAN, so that they can share each other's programs, bugs included. 3 Biggest Software Lies: - The program's fully tested and bugfree. - We're working on the documentation. - Of course we can modify it. 3 Biggest Computer Room Lies: - As long as you remember to 'SAVE' your input, you'll never lose any files. - We run the stuff through as fast as it comes in the door. - The new machines on order. 3 Biggest Large Company Lies: - We have an entrepreneurial spirit here. - People are our greatest resource. - We say 'let the marketplace decide'. 3 Biggest Small Company Lies: - We have an entrepreneurial spirit here. - The boss is just one of the guys. - Staying small is a conscious decision. 3 Biggest Marketing Lies: - Immediate delivery?...No problem. - We treat every customer as if they were our most important. - We're going out to lunch to talk business. 3 Biggest Engineering Professor's Lies: - Some day this course will come in handy. - These tests are more trouble for me than they are for you. - This is the way they do it in industry. 3 Biggest Executive Lies: - Money...it's just a score card. - If it were up to me, there'd be no assigned parking spaces. - You have to twist my arm to get me to go on a business trip. 3 Biggest Hardware Lies: - We always design for testablilty. - It worked fine on the proto board. - That would be much easier to implement in software. THREE PROPOSITIONS ------------------ 1. Software engineering is like looking for a black cat in a dark room. 2. Systems engineering is like looking for a black cat in a dark room in which there is no cat. 3. Knowledge engineering is like looking for a black cat in a dark room where there is no cat and someone yells, "I got it!".
