0x20 Product identification block contains standard vendor and product IDs, serial number, date of manufacture and product name. Comparing to legacy block 0x00, Microsoft ISA Plug&Play identifier is replaced with IEEE OUI, first used in the network MAC address.
First letter of manufacturer ID (byte 8, bits 6–2) Bits 9–5: Second letter of manufacturer ID (byte 8, bit 1 through byte 9 bit 5) Bits 4–0: Third letter of manufacturer ID (byte 9 bits 4–0) 10–11: Manufacturer product code. 16-bit hex number, little-endian. For Example, "PHL" + "C0CF". 12–15: Serial number. 32 bits, little-endian. 16
At the height of COBOL usage in the 1960s through 1980s, the IBM COBOL product was the most important of any industry COBOL compilers. In his popular textbook A Simplified Guide to Structured COBOL Programming , Daniel D. McCracken tries to make the treatment general for any machine and compiler, but when he gives details for a particular one ...

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]
Sylvania Electric Products Inc. was an American manufacturer of diverse electrical equipment, including at various times radio transceivers, vacuum tubes, semiconductors, and mainframe computers such as MOBIDIC. They were one of the companies involved in the development of the COBOL programming language.
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 ...
GnuCOBOL (formerly known as OpenCOBOL, and briefly as GNU Cobol) is a free implementation of the COBOL programming language that is part of the GNU project. GnuCOBOL translates the COBOL code into C and then compiles it using the native C compiler .
