ANSI X3.26-1980 (R1991) Hollerith Punched Card Code; ISO 1681:1973 Information processing – Unpunched paper cards – Specification; ISO 6586:1980 Data processing – Implementation of the ISO 7- bit and 8- bit coded character sets on punched cards. Defines ISO 7-bit and 8-bit character sets on punched cards as well as the representation of 7 ...
Hollerith started his own business as The Hollerith Electric Tabulating System, specializing in punched card data processing equipment. [10] In 1896 he incorporated the Tabulating Machine Company. In that year he introduced the Hollerith Integrating Tabulator, which could add numbers coded on punched cards, not just count the number of holes.

It is an eight-bit character encoding, developed separately from the seven-bit ASCII encoding scheme. It was created to extend the existing Binary-Coded Decimal (BCD) Interchange Code, or BCDIC, which itself was devised as an efficient means of encoding the two zone and number punches on punched cards into six bits. The distinct encoding of 's ...
Hollerith constants, named in honor of Herman Hollerith, were used in early FORTRAN programs to allow manipulation of character data. Early FORTRAN had no CHARACTER data type , only numeric types. In order to perform character manipulation, characters needed to be placed into numeric variables using Hollerith constants.
The Microsoft Reader's .lit file format is a modification of the HTML Help CHM format. CHM files are sometimes used for e-books. [13] Sumatra PDF supports viewing CHM documents since version 1.9. Various applications, such as HTML Help Workshop and 7-Zip can decompile CHM files. The hh.exe utility on Windows and the extract_chmLib utility (a ...
You can add a table using HTML rather than wiki markup, as described at HTML element#Tables. However, HTML tables are discouraged because wikitables are easier to customize and maintain, as described at manual of style on tables. Also, note that the <thead>, <tbody>, <tfoot>, <colgroup>, and <col> elements are not supported in wikitext.
A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...
