Share Your ExperienceProduct Overview
SAA RPG/370's architecture comprised several key components. The compiler translated RPG source code into object code. The linker combined object modules into executable programs.
The runtime environment provided the necessary services for program execution. The system utilized a hierarchical file system for data storage. Communication relied on standard mainframe protocols.
The compiler generated object code that was then linked and executed on the z/OS platform. The system did not expose APIs. The primary data storage mechanism was the VSAM file system.
Security was handled through z/OS security features. The administrative interface was primarily through JCL and system utilities. The product's end of support necessitates migration to supported languages such as COBOL or Java.
IBM Rational Open RPG/I offers a migration path. The architecture was based on the IBM System/370 architecture. The compiler generated object code that was then linked and executed on the z/OS platform.
For integration, developers would interact with the system through JCL and system utilities.
