The present invention is directed to a system for for automated interface generation for computer programs operating in different environments. The system comprises a utility which imports a CICS COBOL transaction source file, parses the communication area of the CICS file, and generates modelling information. The modelling information represents the nature and structure of data in the CICS transaction source file, and is written to a persistent data store. The utility uses the information in the persistent data store to generate an application programming interface. The application programming interface takes the data values from the other language and translates them to a formatted CICS COBOL communications area. This format is derived from the definition of the CICS communications area contained in the imported CICS program. After the translation runs, the resulting CICS COBOL communications area is translated back to the data values of the other language. This translation step also handles the data conversion between different codepages and machine architectures and program semantics. The resulting language values represent the result of the transaction. The CICS transaction is accessed using the CICS External Call Interface mechanism.

An efficient program analysis method is provided for lazily decomposing aggregates (such as records and arrays) into simpler components based on the access patterns specific to a given program. This process allows us both to identify implicit aggregate structure not evident from declarative information in the program, and to simplify the representation of declared aggregates when references are made only to a subset of their components. The method can be exploited to yield: (i) a fast type analysis method applicable to program maintenance applications (such as date usage inference for the Year 2000 problem); and (ii) an efficient method for atomization of aggregates. More specifically, aggregate atomization decomposes all of the data that can be manipulated by the program into a set of disjoint atoms such that each data reference can be modeled as one or more references to atoms without loss of semantic information. Aggregate atomization can be used to adapt program analyses and representations designed for scalar data to aggregate data. In particular, atomization can be used to build more precise versions of program representations such as SSA form or PDGs. Such representations can in turn yield more accurate results for problems such as program slicing. Our techniques are especially useful in weakly-typed languages such as Cobol (where a variable need not be declared as an aggregate to store an aggregate value) and in languages where references to statically-defined sub-ranges of data such as arrays or strings are allowed.

A computer-implemented system or process is programmed or configured to use a configuration file to specify one or more tasks to apply to raw ingested data. A task may be a sequence of instructions programmed or configured to format raw ingested data into a dataset in a CSV format. Examples of tasks may include: a parser to parse Cobol data into a CSV, a parser to parse XML into a CSV, a parser to parse text using fixed-width fields to a CSV, a parser to parse files in a zip archive into a CSV, a regular expression search/replace function, or formatting logic to remove lines or blank lines from raw ingested data. In one embodiment, the configuration file may specify a schema definition for a task to use for generating a dataset. In one embodiment, the configuration file may also include one or more access control list (ACL) definitions for the generated dataset. In one embodiment, the building of datasets using the configuration file is automated, for example, on a nightly basis.

The approach includes a compilation (or translation) step utilizing a first compiler or translating program which is a parallel aware translating first compiler. The parallel aware first compiler is a specialized compiler/translator which takes as input a Cobol source program, and produces as output an intermediate computer program in a second computer programming language, the intermediate program including parallelization directives, the intermediate program intended for further compilation utilizing an existing selected second compiler, the second compiler providing support for parallelism for programs described in the second programming language. The approach optionally allows for use of pragmas serving as parallelization directives to the compiler in the original Cobol program or in the intermediate program.

A method, apparatus, and program for translating source code programs from COBOL into an object-oriented language and then utilize an “object” that emulates the COBOL's Working-Storage Section. By emulating the Working-Storage Section in an object-oriented program, the object-oriented program source code can closely resemble the original COBOL source code as well as have a very clean syntax. This allows it to be kept in a highly maintainable and readable form after translation.

As manufacturers of very fast and powerful commodity processors continue to improve the capabilities of their products, it has become practical to emulate the proprietary hardware and operating systems of powerful older computers on platforms built using commodity processors such that the manufacturers of the older computers can provide new systems which allow their customers to continue to use their highly-regarded proprietary legacy software on state-of-the-art new computer systems by emulating the older computer in software that runs on the new systems. In an example of the subject invention, a 64-bit Cobol Virtual Machine instruction provides the capability of adding to or improving the performance of legacy 36-bit Cobol code. Legacy Cobol instructions can be selectively diverted, in the host CPU, to a 64 bit Virtual Machine Implementation. The output legacy and new Cobol code is compiled in a dedicated implementation of the Cobol compiler, and the output of the special purpose compiler is emulated in a special purpose software emulator, separate from the main software emulator that handles the normal 36-bit stream of legacy code.

Automated interface generation for computer programs operating in different environments is provided. An automated interface generation system, method, computer program product and article of manufacture is provided comprising an import utility and a runtime environment. The import utility imports a COBOL IMS transaction source file, parses the specified input and output message records, and generates an application programming interface. The application programming interface operates with the runtime environment to take the data values from the language of a different environment and translate them to a formatted IMS input message. This format is derived from the definition of the input message record in the COBOL IMS transaction source file. After the IMS transaction has executed, the resulting IMS output message is translated back to the data values of the language of the different environment, said values including the results of the transaction. The translation step handles data conversion between different code pages, machine architectures, and program semantics, and handles the dynamic nature of IMS messages.

The present invention provides copybook flat data conversion with inline transformation. Specifically, a streaming intermediary formatted data message is generated as a result of converting/transforming a flat file format (non-XML (Extensible Markup Language) format), such as raw fixed-length field COBOL (Common Business-Oriented Language) copybook format or the like. The streaming intermediary format is not fully held in memory, but rather is directly transformed/converted, using XSLT (Extensible Stylesheet Language Transformations) processing, into a target format, such as structured XML or the like. By directly streaming the intermediary format to the XSLT process without holding the entire data message in memory, the present invention utilizes less memory and, as such, less memory is needed to be reclaimed.

A tilting tree, spinning cones process is employed to map n-dimensional array data originally in markup language, to an n-dimension table suitable for use by COBOL application programs. Mapping is performed without scanning the result array for an empty slot. This allows the result array slots to be pre-loaded with state data. During mapping, the hierarchical nature of the markup language n-dimensional data is represented in two-dimensions using an inverted tree structure having cones for each array level. The tree is tilted to bring a member of a given level into contact with one of the axes of the tree graph, followed by spinning appropriate cones to bring a certain member of that level into contact with the same axis. This results in the ability to use a one-dimensional mapping array. The dimension offset on the mapping axis can then be used as an index value into the mapped array output for storage or retrieval of element data.
