This article is about the ARGUS language and machine language of the Honeywell 800 and 1800 computers. The name ARGUS was an acronym standing for Automatic Routine Generating and Updating System.〔(Company Sales Manual for the Honeywell 1800 )〕 ARGUS was an Assembly Language devised in the 1960s by Honeywell for their Honeywell 800 and 1800 computers. As with other Assembly Languages, each line of ARGUS was copied on to one card and related to one word in memory, except that one ARGUS command, RESERVE, could reserve any specified number of words in the position specified. The RESERVE command was also exceptional in not prescribing the initial data in the reserved words. With a few exceptions Machine Language words were coded in the same order as the ARGUS lines .〔The initial author of this article programmed a Honeywell 1800 for Eastern Electricity Board, UK from January to August 1966 and this article is mainly written from memory. If anyone has documentary material and can review and correct the article, providing inline references, that would be useful. This information is broadly correct but a few errors of detail may be found. It seems better to write some article from memory than wait for a fully referenced article that may never emerge. Honeywell was a significant force in the embryo computer industry and its work is worth recording〕 ==Honeywell 800 Memory== The Honeywell 800 and 1800 had a main memory and a control memory, both using ferrite cores. The main memory had between 4 and 16 banks, depending on customer requirements. Each bank contained 2048 words of 48 bits each. The actual number of banks in an individual installation had to be a multiple of 4.〔 The control memory had 256 registers of 16 bits each. At any given time the machine could theoretically run one Operating System and 7 application programs, each with exclusive use of 32 registers.〔 A program that required more than 2048 words (data and instructions combined) had to be split into segments of 2048 words or less. Each segment would have exclusive use of one bank of main memory. There were special instructions to pass control from one segment to another. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Honeywell ARGUS」の詳細全文を読む スポンサード リンク
