Single code set applications executing in a multiple platform system

摘要

Embodiments of the claimed subject matter are directed to methods and a system that allows an application comprising a single code set under the COBOL Programming Language to execute in multiple platforms on the same multi-platform system (such as a mainframe). In one embodiment, a single code set is pre-compiled to determine specific portions of the code set compatible with the host (or prospective) platform. Once the code set has been pre-compiled to determine compatible portions, those portions may be compiled and executed in the host platform. According to these embodiments, an application may be executed from a single code set that is compatible with multiple platforms, thereby potentially reducing the complexity of developing the application for multiple platforms.

主权项

1. A computer-implemented method comprising:
obtaining a set of computer instructions associated with a software application; identifying, by a computing platform on which the set of computer instructions are to be executed, portions of the computer instructions that are each immediately preceded by a respective platform-specific, platform verification subroutine; before compiling the set of computer instructions, invoking, by the computing platform on which the set of computer instructions are to be executed, each of the platform-specific, platform verification subroutines, and identifying the platform-specific, platform verification subroutines that successfully complete; compiling, by the computing platform on which the set of computer instructions are to be executed, a proper subset of the computer instructions, including compiling one or more of the portions of the computer instructions that are immediately preceded by the platform-specific, platform verification subroutines that successfully complete without compiling one or more of the portions of the computer instructions that are immediately preceded by the platform-specific, platform verification subroutines that did not successfully complete; and executing, by the computing platform, the compiled computer instructions.
