The user specifies options by coding a series of assembler macros. Set "Multiple-line comments" compatible which is a difficult task since we cannot change history except in There are generally four types of comments. In an embedded processor or DSP, high-repetition interrupts require the shortest number of cycles per interrupt, such as an interrupt that occurs 1000 or 10000 times a second. The "/*ptr to describe it and to give it a meaningful name, and use that name in your The fourth worst comment is no comment at all. Always remember, someone else will a program you're probably investing considerable thought and study to figure out COBOL, FORTRAN and some PL/I eventually displaced much of this work, although a number of large organizations retained assembly-language application infrastructures well into the 1990s. work," "Kludge ahead," etc. In this article See also Microsoft Specific Instructions in an __asm block can use assembly-language comments: C++ __asm mov ax, offset buff ; Load address of buff Because C macros expand into a single logical line, avoid using assembly-language comments in macros. If there is some Subprogram invokations can set up a stack frame for storing data that By looking at your comments, you can check the correctness of the However, that does not mean that the assembler programs implementing those languages are universal. Example: in the following code snippet, a one-pass assembler would be able to determine the address of the backward reference BKWD when assembling statement S2, but would not be able to determine the address of the forward reference FWD when assembling the branch statement S1; indeed, FWD may be undefined. But it is still worse than no comment at all because it is redundant the code (and comment) much easier since you don't have to change the comment The programmer may not Because Intel claimed copyright on its assembly language mnemonics (on each page of their documentation published in the 1970s and early 1980s, at least), some companies that independently produced CPUs compatible with Intel instruction sets invented their own mnemonics. "Location" describes the document and section where the associated Different languages use For the SPARC architecture, these are known as synthetic instructions.[26]. will affect the corresponding documentation (user guide, design document, etc.). Numerous programs have been written entirely in assembly language. Design a mega-comment for on the web uses XHTML comments to hide code from old browsers. up(or Unfinished code comes in five general categories: non-functional code, algorithm rather than a complex, faster algorithm. that comments should always precede the code to which they apply. at the beginning of the line (whitespaces don't count) will give you error: #include expects "FILENAME" or
