Cobol/Cobol Database Interface.Htm Copyright © Tutorialspoint.Com
CCOOBBOOLL -- DDAATTAABBAASSEE IINNTTEERRFFAACCEE http://www.tutorialspoint.com/cobol/cobol_database_interface.htm Copyright © tutorialspoint.com As of now, we have learnt the use of files in COBOL. Now, we will discuss how a COBOL program interacts with DB2. It involves the following terms: Embedded SQL DB2 Application Programming Host Variables SQLCA SQL Queries Cursors Embedded SQL Embedded SQL statements are used in COBOL programs to perform standard SQL operations. Embedded SQL statements are preprocessed by SQL processor before the application program is compiled. COBOL is known as the Host Language. COBOL-DB2 applications are those applications that include both COBOL and DB2. Embedded SQL statements work like normal SQL statements with some minor changes. For example, that output of a query is directed to a predefined set of variables which are referred as Host Variables. An additional INTO clause is placed in the SELECT statement. DB2 Application Programming Following are rules to be followed while coding a COBOL-DB2 program: All the SQL statements must be delimited between EXEC SQL and END-EXEC. SQL statements must be coded in Area B. All the tables that are used in a program must be declared in the Working-Storage Section. This is done by using the INCLUDE statement. All SQL statements other than INCLUDE and DECLARE TABLE must appear in the Procedure Division. Host Variables Host variables are used for receiving data from a table or inserting data in a table. Host variables must be declared for all values that are to be passed between the program and the DB2. They are declared in the Working-Storage Section. -

C21-908-101 Programmable Terminals Wang Laboratories 2200 Series MANAGEMENT SUMMARY A series of five minicomputer systems that Wang Laboratories' 2200 Series product line currently offer both batch and interactive communica consists of the 2200VP, 2200MVP, 2200LVP and tions capabilities. 2200SVP processors, all of which are multi-user or multi user upgradeable systems. The 2200 Series product line Emulation packages are provided for standard also includes the 2200 PCS-I1I, a packaged system which Teletype communications; IBM 2741 emula is single-user oriented. tion; IBM 2780, 3780, and 3741 batch terminal communications; and IBM 3270 The CPU and floppy disk drive are packaged together interactive communications. with appropriate cables and a cabinet to produce an integrated system. The 2200 PCS-I1I includes the CPU, A basic 2200PCS-1II with 32K bytes of user CRT, keyboard and single-sided double density memory, a CRT display, and a minidiskette minidiskette drive in a standard CRT-size enclosure as drive is priced at $6,500. Prices range well as an optional disk multiplexer controller. The upward to $21,000 for a 2200MVP proc number of peripherals that can be attached to a given essor with 256K bytes of user memory, system depends on the number of I/O slots that are excluding peripherals. Leases and rental plans available, with most peripherals requiring one slot. In all are also available. 2200 Series CPUs, highly efficient use of memory is achieved through the use of separate control memory to store the BASIC-2 interpreter and operating system. CHARACTERISTICS Wang began marketing the original 2200 Series in the VENDOR: Wang Laboratories,lnc., One Industrial Avenue, Spring of 1973. -

The name change was claimed to have taken place to evade military service. But this story seems to be invalid as all census records for him and his sons use the name Super. 1.

An Array-Oriented Language with Static Rank Polymorphism
An array-oriented language with static rank polymorphism Justin Slepak, Olin Shivers, and Panagiotis Manolios Northeastern University fjrslepak,shivers,[email protected] Abstract. The array-computational model pioneered by Iverson's lan- guages APL and J offers a simple and expressive solution to the \von Neumann bottleneck." It includes a form of rank, or dimensional, poly- morphism, which renders much of a program's control structure im- plicit by lifting base operators to higher-dimensional array structures. We present the first formal semantics for this model, along with the first static type system that captures the full power of the core language. The formal dynamic semantics of our core language, Remora, illuminates several of the murkier corners of the model. This allows us to resolve some of the model's ad hoc elements in more general, regular ways. Among these, we can generalise the model from SIMD to MIMD computations, by extending the semantics to permit functions to be lifted to higher- dimensional arrays in the same way as their arguments. Our static semantics, a dependent type system of carefully restricted power, is capable of describing array computations whose dimensions cannot be determined statically. The type-checking problem is decidable and the type system is accompanied by the usual soundness theorems. Our type system's principal contribution is that it serves to extract the implicit control structure that provides so much of the language's expres- sive power, making this structure explicitly apparent at compile time. 1 The Promise of Rank Polymorphism Behind every interesting programming language is an interesting model of com- putation. -
Is Ja Dialect of APL? Reported by Jonathan Barman Eugene Mcdonnell - the Question Is Irrelevant
VICTOR Vol.8 No.2 convert the noun back to verb and as a result various interesting control structures can be created. The verbal nouns thus formed can be put into arrays and some of the benefits that various people have suggested might arise from arrays of functions can be obtained. A design goal is to make compilation possible without limiting the expressive power of J. APL Technology of Computer Simulation, by A Boozin and I Popselov reported by Sylvia Camacho Both authors of this paper are academic mathematicians and their use of APL is just where one might expect it to be: in modelling linear differential equations and stochastic Markovian processes. Questions put showed that they first used APL 15 years ago on terminals to what was described as 'a big old computer'. Currently they use APL*PLUS/PC. They have set up an environment in which they can split the screen and display data graphically with some zoom facilities. This environment can be used in conjunction with raw APL while exploring the results of a model, or can be used in conjunction with data derived from APL or some other source. In fact it is often used by Pascal programmers. Most recently they have been setting up economic models to try to come to terms with the consequences of decentralisation and privatisation. They use both Roman and Cyrillic alphabets. Panel: Is Ja Dialect of APL? reported by Jonathan Barman Eugene McDonnell - The question is irrelevant. Surely proponents of J would not be thrown out of the APL community? Garth Foster - J is quite definitely not APL. -
