  2. Standard Commands for Programmable Instruments - Wikipedia

    en.wikipedia.org/wiki/Standard_Commands_for...

    Arguments are given after the command, and are separated from the command using a space. [11] For example, the command to set the trigger mode of an instrument to "normal" may be given as "TRIGger:MODe NORMal". Here, the word "NORMal" is used as the argument to the "TRIGger:MODe" command. When multiple arguments are provided, the arguments are ...

    Example using APL to index ⍳ or find (or not find) elements in a character vector: First, variable Letters is assigned a vector of 5-elements, in this case - letters of the alphabet. The shape ⍴ or character vector-length of Letters is 5. Variable FindIt is assigned what to search for in Letters and its length is 4 characters.

  4. Symbol table - Wikipedia

    en.wikipedia.org/wiki/Symbol_table

    In computer science, a symbol table is a data structure used by a language translator such as a compiler or interpreter, where each identifier, symbol, constant, procedure and function in a program's source code is associated with information relating to its declaration or appearance in the source. In other words, the entries of a symbol table ...

  5. Cyclic redundancy check - Wikipedia

    en.wikipedia.org/wiki/Cyclic_redundancy_check

    The advantage of choosing a primitive polynomial as the generator for a CRC code is that the resulting code has maximal total block length in the sense that all 1-bit errors within that block length have different remainders (also called syndromes) and therefore, since the remainder is a linear function of the block, the code can detect all 2 ...

  6. Naming convention (programming) - Wikipedia

    en.wikipedia.org/wiki/Naming_convention...

    To reduce the effort needed to read and understand source code; [1] To enable code reviews to focus on issues more important than syntax and naming standards. To enable code quality review tools to focus their reporting mainly on significant issues other than syntax and style preferences.

  7. Abstract syntax tree - Wikipedia

    en.wikipedia.org/wiki/Abstract_syntax_tree

    An abstract syntax tree (AST) is a data structure used in computer science to represent the structure of a program or code snippet. It is a tree representation of the abstract syntactic structure of text (often source code) written in a formal language. Each node of the tree denotes a construct occurring in the text.

    Since each location on the board can be either empty, black, or white, there are a total of 3 n 2 possible board positions on a square board with length n; however not all of them are legal. Tromp and Farnebäck derived a recursive formula for legal positions L ( m , n ) {\displaystyle L(m,n)} of a rectangle board with length m and n . [ 9 ]
