Use of IBM COBOL was so widespread that Capex Corporation, an independent software vendor, made a post-code generation phase object code optimizer for it. [3] The Capex Optimizer became a quite successful product. [4] Although the IBM COBOL Compiler Family web site [5] only mentions AIX, Linux, and z/OS, IBM still offers COBOL on z/VM and z/VSE.
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 ...
An 88 level-number declares a condition name (a so-called 88-level) which is true when its parent data item contains one of the values specified in its VALUE clause. [142] For example, the following code defines two 88-level condition-name items that are true or false depending on the current character data value of the wage-type data item.
Various serial peripherals were attached: Printronix bar-coding printers, MICR Readers, IBM ASCII Terminals. Parallel devices were also used for phototypesetting machines, plate makers and Teletype BRPE punch creating Punched tape; all connecting to the IBM integrated DI/DO digital in/out card. The Series/1 was a good work horse for its day and ...
COBOL uses the syntax WRITE record-name AFTER ADVANCING n Lines., where record-name is the name of the area containing the line and n is the number of lines. Additionally BEFORE ADVANCING can be used or BEFORE|AFTER ADVANCING TOP to skip to the top of a new page. [1]
It is used in character data on IBM mainframes by languages such as COBOL, PL/I, and RPG. [1] Its purpose is to save a character that would otherwise be used by the sign digit. [2] The code is derived from the Hollerith Punched Card Code, where both a digit and a sign can be entered in the same card column. It is called an overpunch because the ...
It consists of three fields, including an 8-bit regional code (RR), a 24-bit manufacturer code, and a 24-bit manufacturer-assigned serial number. The check digit (CD) is not considered part of the MEID. The MEID was created to replace electronic serial numbers (ESNs), whose virgin form was exhausted in November 2008. [1]
The term serial number is sometimes used for codes which do not identify a single instance of something. For example, the International Standard Serial Number or ISSN used on magazines, journals and other periodicals , an equivalent to the International Standard Book Number (ISBN) applied to books, is assigned to each periodical .
