INTERCAL manual. The culprits have sensibly declined to identify themselves .) INTERCAL was inspired by one ambition: to have a compiler language which. Donor challenge: Your generous donation will be matched 2-to-1 right now. Your $5 becomes $15! Dear Internet Archive Supporter,. I ask only. The inventors of INTERCAL implemented it, had a few laughs, and quickly forgot about it. However, the language manual lived on. The documentation itself was.

MAYBEnot enabled:. This runtime error usually indicates a logic mistake in your program. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute.
The following instructions will help you install the distribution in a method appropriate for your system. Here’s a transcript of a article by Charles Stross. If there happen to be multiple labels with the maual value at the time, the compiler will NEXT to one of them. ONCE specifies that the statement is self-abstaining or self-reinstating this will be explained below ; AGAIN specifies that the statement should behave like inhercal has already self-reinstated or self-abstained.
Grouping imtercal get complicated when nested array intercaal is used, particularly with multiple subscripts. The onespot and twospot ranges become the highest number of trits or other digits in the maanual required that fit inside the binary ranges, so for instance, the maximum value of a onespot variable in ternary isor 3 to the power 10 minus 1.
The internal error E see E should never happen. If it exists, it must be the very last command in the program it cannot even be followed by syntax errorsand it causes execution of the program to go back to the first command. These are represented with a spot, twospot, tail, and hybrid. One way to obtain the latest cfunge sources is via the bzr version-control system, using the following command correct as of the time of writing, but as always, links can become dead:.
The INTERCAL Programming Language Revised Reference Manual
This seems to have languages covered inhercal well; what on earth were you using, or did you just make a spelling mistake? The difference between a standalone line label and a line label that labels a statement is that COME Intercaal s will come from the label itself which is before the next statement when aiming at a standalone line label, but the end of the statement when aiming at a labeled statement.
Little code has ever been written in INTERCAL, most wimps being content to just read the manual, so it will be interesting to see what new and horrible things can yet be accomplished with the language. Brainfuck — A Turing-complete language in just eight instructions. If you think that intrcal has gone wrong with the parser, or you want to see how your program is being parsed, you can give this option on the command line.
Expressions are made up out of operands and operators between them. They can reference the following variables and functions:. If the variable, or the array that contains the array element, happens to be read-only, the input or output still happens but ibtercal the case of WRITE IN silently skips the assignment, instead throwing away the input.
It is even permitted to label a block statement in this way. On DJGPP, ick creates temporary files to pass options to gcc as a method of getting around the limit on the length of a command line that can sometimes affect DOS programs. It can be used within any function regardless of how it was declared, and never returns; instead, it pops the specified number of NEXT stack entries and resumes execution at the last one popped, just as the INTERCAL statement does.
Although the three identifiers have the same meaning, using either polite or non-polite identifiers too much can cause an error; the correct proportion is approximately 3 non-polite identifiers for every polite identifier used.
In other projects Wikimedia Commons. Likewise, the first time a self-reinstating statement is encountered, it is not executed as is normal for an abstained statementbut then becomes reinstated and will run in future. Move over, Ruby manul Rails!
The profiler will, in fact, identify all the timings that particular commands in the program take; so WRITE IN instructions will often show up as taking a long time due to their need to wait for input. This option is not necessarily needed for the external call version of CREATE to work, but the external call version has fewer features without it. Their prototypes are as follows:. Nowadays, there are other ways to write the required characters than using backspace; for instance, the cent sign appears in Latin-1 and UTF-8, and there are various characters that approximate bookworms for instance, CLC-INTERCAL uses the Latin-1 yen symbol for this, which just to make things confusing, refers to a mingle in modern Atari syntax.
Support for Funge does not ship with the compiler; instead, you need to generate the library yourself from the cfunge sources. The syntax of a calculate command is as follows:. NET Implementation targeting the. This option is occasionally capable of doing something, but is deliberately undocumented.
There are two types of operators, unary and binary operators, which operate on one and two arguments respectively.
The Intercal Programming Language Reference Manual
As in Manuaalthere is no operator precedence; expressions must be very fully bracketed to ,anual unambiguously what the precedences must be, and then more so; for instance, bracketing marks must be placed around the argument of a unary operator in most circumstances. DO line NEXT branches to the line specified, remembering the next line that would be executed if it weren’t for the NEXT on a call stack other identifiers than DO can be used on any statement, DO is given as an example ; DO FORGET expression removes expression entries from the top of the call stack this is useful to avoid the error that otherwise happens when there are more than 80 entriesand DO RESUME expression removes expression entries from the call stack and jumps to the last intdrcal remembered.
Character-based output uses a similar model, but conceptually the output device moves on the inside of the tape, rather than on the outside.
Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. This error should never happen, and if it manuzl indicates a compiler bug. Going past the last command manusl the program is an error. The mingle operator should be applied to two operands or expressions.
You eat assemblers for breakfast. This option causes the program to run immediately after being compiled, and profiles the resulting program to identify performance bottlenecks, etc. This error comes up if you use nonpositive or twospot values for a line label. Step aside, Cobol on Cogs!
From then on, all the threads run simultaneously. In order for the code there to be able to affect the variables mentioned in the statement, iintercal variables:
