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.

I have not investigated whether it might be more efficient to return ingercal terminate immediately after the first overflow, instead of working through the entire exponent. This function returns its argument selected with itself; so xselx c is shorthand for iselect c,c.
When using a character set where not all bits in each byte are specified, a third argument can be given to specify what sort of nitercal to use for the top bits of each character.
That is, a value is calculated at optimise-time and the resulting value is therefore constant at runtime. In keeping with the best C traditions, these caveats are not checked, but instead result in undefined behaviour if breached.
Abandon All Sanity, Ye Who Enter Here
Giving this option causes the compiler to stop when it has finished producing the C file, leaving the C file there as the final output of the compiler. For inconsistency, it is possible to have multiple lines with the same number as long as at most one of them is in an INTERCAL program the others have to inetrcal in programs in other languages included via the external calls system.
Reinstating a statement always de-abstains it exactly once; so double-abstaining from a statement, for interca, means it needs to be reinstated twice before it will actually execute. This option allows debugging of the final executable at the C code level. You can also avoid the problem by marking variables as volatile in the C program. 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 intercsl more than 80 entriesand DO RESUME expression removes expression entries from the call stack and jumps to the last line remembered.
It satirizes aspects of the various programming languages at the time,  as well as the proliferation of proposed language constructs and notations in the s. Replacement operands are simpler than pattern operands, because there are only a few forms they can take. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.
You may wonder why this bug was preserved; it is in fact a bug that was carefully preserved since the days of INTERCALin this case, but the option to turn it off is available as a workaround. ONCE specifies that the statement is self-abstaining or self-reinstating this will be explained below ; AGAIN specifies that the statement should behave like it has already self-reinstated or self-abstained.
This is a list of the warnings stored in the warning database. They look like this:. Commands are single characters followed by newlines, or intercsl by a interca number in decimal and a newline or a variable name a.
Control constructs that will make you gasp, integcal you laugh, and possibly make you hurl. The syntax for an array element is the array, followed by the keyword SUBfollowed by an expression for the element number in the array.
If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed as many as fit reasonably on the actual cover, and continue the rest onto adjacent pages. If you are using NEXT s like procedures, then this effectively means that the procedure will run until it returns. You may include a translation of this Maunal, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers.
This will include stdint. The output will be saved in a file mamual yuk. This error is like E see Ebut applies when an attempt is made at runtime to store a threespot value or even a fourspot or morespot value in a twospot variable, or a threespot intercl greater value is produced as an intermediate during a calculation for instance by a mingle operation.
Both covers must also clearly and legibly identify you as the publisher of these copies.
Warnings only come up when the -l option see -l is given; even manial, some of the warnings are not currently implemented and therefore will never come up. Either the label or the manul identifier, whichever one comes first, marks where the preceding statement finishes. This applies even if the command in question is in fact a syntax error, thus causing this to be a useful method of writing comments.
An image format is not Transparent if used for any substantial imtercal of text. The operand matches any constant integer which has no bits in common with AAAAAAAA, and for which if manula bit in common with is set, all less significant bits in common with that number are also set.
This error comes up if you use nonpositive or twospot values for a line label. There is one exception, in that if two or more left-hand commands end in a space of time in which no right-hand commands for that WHILE ends, they together only cause one right-hand command to end. All of the above routines except,and also modify.

C-INTERCAL Revamped Instruction Manual
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 manyal a mingle in modern Atari syntax.
Backtracking in a thread see Backtracking causes it to unweave with any threads it may be woven with at the time so the data in the thread that backtracks is set back to the data it, and the threads it was woven intrrcal at the time, had at the time of the MAYBEbut the other threads continue with the same data as before.
This option needs to be given to allow any multithreading or backtracking commands or identifiers to be used. Bracketing of expressions can be done with parentheses, sparks apostrophes or rabbit-ears double-quotes. Grouping can get complicated when nested array subscripting is used, particularly with multiple subscripts.
The INTERCAL Programming Language Revised Reference Manual
mamual For similar reasons, the expansion libraries syslibc. This error happens at run time when the subscripts given to an array are inconsistent with the way the array was dimensioned, either because there were the wrong number of subscripts or because a subscript was too large to fit in the array.
External Calls to Funge 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. Intercaal is a well-known and oft-demonstrated fact that a person whose work is incomprehensible is held in high esteem.
