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.

However, you may accept compensation in exchange for copies. Also, sometimes they require changing the value of a constant; this is only legal if you specifically specified that it was legal by using the -v option. While such a convenience feature might be judged not in the spirit of INTERCALthe required level of perversity is arguably restored by the way inclusion is triggered: This is so that code like.
The anything provides an example statement to CREATE ; statements which look the same but may differ in details are created.
C-INTERCAL Revamped Instruction Manual
This example is provided mostly just to demonstrate the syntax, and the care that needs to be taken with implementing flow control operators. All the debug output produced by the parser and lexical analyser will be interval. In such a case, you would do nothing other than possibly edit the program to be more portable and a possible character set and syntax change using convickt.
The smudgeright function returns its argument but with all the bits less significant than the most significant bit with value 1 set to 1; likewise, smudgeleft returns its argument with all the bits more significant than the least significant bit with value 1 set to 1.
If PLEASE was not encountered often enough, the program would be rejected; that is, ignored without explanation by the compiler. This will include stdint.
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. At the beginning of the program, all variables stand for themselves; so. There is also computed CREATEworking identically to ordinary CREATE except that the line number is taken from an expression and the created command must start with a letter to avoid an ambiguity if the expression giving the line label happens to be an array referencewith a syntax like this:.
However, the present optimizer is incapable of recognising whether this problem exists or not, so the warning is not currently implemented. To be portable, the operands must both be onespot expressions, that is expressions which have a bit result; C-INTERCAL relaxes this rule slightly and only requires that the result be in the onespot range.
The command pushes information about the argument chosen onto the stack; the following information is pushed from bottom to top:. This option also allows you to write arbitary expressions on the left of an assignment statement if you wish. Differences to Other Compilers. Whitespace is generally insignificant in INTERCAL programs; it cannot be added in the middle of a keyword unless the keyword contains whitespace itself or inside a decimal number, but it can be added more or less anywhere else, and it can be removed from anywhere in the program as well.
The result is a bit value that is, it is of a bit data type, even if its value fits into the onespot rangewhich consists of bits alternated from the two arguments; to be precise, its most significant bit is the most significant bit of its first argument, its second most significant bit is the most significant bit of its second argument, its third most significant bit is the second most significant bit of its first argument, and so on until its least significant bit, which is the least significant bit of its second argument.
This “forgiving” feature makes finding bugs very difficult; it also introduces a unique system for adding program comments.
As a licensing note, note that cfunge is licensed under the GNU General Public licence version 3, whereas C-INTERCAL is licensed under version 2 and all later versions of that licence; although these terms are obviously compatible with each other, you must ensure yourself that your program has appropriate licensing terms to allow a GPLv3 library to be linked to it.
The only solutions to this are to simplify your program, or to make more memory available to the compiler. The INTERCAL floating-point library uses the IEEE format for bit floating-point numbers, which uses bit 31 as a sign bit 1 being negativebits 30 through 23 hold the exponent with a bias ofand bits 22 through 0 contain the fractional part of the mantissa with an implied leading 1.
C-INTERCAL 0.29 Revamped Instruction Manual
Once the compiler runs and produces an output executable, that executable itself will accept a range of options that control the way it runs.
You can go even further and use make veryclean which will delete not only files created by configuring, but the entire build system; doing so is not recommended unless you have some method of rebuilding the build system from its original sources a script to do this is provided in repository versions of C-INTERCALbecause the generated part of the build system is not stored in the repository. If the variable, or the array that contains the array element, happens to be read-only, the input or output still happens but in the case of WRITE IN silently skips the assignment, instead throwing away the input.
You could send them to me, but it might be better to post to alt.
Abandon All Sanity, Ye Who Enter Here
If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain mabual material copied from the Document, you may at your option designate some or all of these sections as invariant. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. Similar considerations apply to the common nonstandard C extension allocawhich dynamically alters the size of the stack; also, in what goes below, register amnual should be considered to be autobecause the compiler may choose to allocate them on the stack.
You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided manuaal you follow the rules of this License for verbatim copying ontercal each of the documents in all other respects. This warning is meant to detect such mistakes, but is not currently implemented.
In Cit could read as follows:. For instance, I untercal come across proprietary versions of lex that need directives in the source file to say in advance how much memory the lexer-generator needs to allocate. Try using shorter or fewer filenames on the command line, to reduce the risk of such an overflow.
The INTERCAL Programming Language Revised Reference Manual
In the case of an impossible reverse assignment including a situation in which operand overloading causes a reverse assignment to happenthis error happens at runtime. There are two forms of each, one which takes a single line label which must be constant in most compilers, but can instead be an expression in recent CLC-INTERCAL versionsand one which takes an intersection-delimited list of gerunds.
Constants can have any integer value from 0 to inclusive; higher values up to can be generated in programs, but cannot amnual specified literally as constants. Displays a summary of what each command does.
