Rational Development Studio for i

IBM Rational Development Studio for i provides RPG, COBOL, C, and C++ compilers for creating IBM i applications. Rational Development Studio for i provides enhancements to the IBM i host Integrated Language Environment (ILE) compilers for creating and maintaining IBM i applications.

  • ILE RPG compiler: Includes the productivity features of RPG IV and the ILE common runtime environment to deliver a powerful programming language.
  • ILE COBOL compiler: Provides functions to enhance your programming tasks.
  • ILE C and C++ compilers: Provides a high-performance, high-function compiler for C development on the IBM i platform as well as a C++ compiler that provides additional features not found in the C language.
  • Application Development Toolset (ADTS): Offers an integrated set of host-based development tools and is an optional feature of Rational Development Studio for i.

ILE RPG compiler

  • Supports integers, floating point, variable length fields, unicode, parameters passed by value, return values, null terminated strings, pointers and pointer arithmetic, long names, and dynamic storage management.
  • Provides options for XML-INTO for improved flexibility.
  • Searches and sorts data structure arrays.
  • Includes ALIAS names support, built-in functions, optional prototypes, and implicit parameter conversion between alphanumeric, USC-2, and graphic data types.

ILE COBOL compiler

  • Support for ANSI-85 functions to port code from other platforms to IBM i.
  • Supports the COMPUTATIONAL-5 or COMP-5 native binary data type.
  • Compiles very large programs by disabling optimization with OPTIMIZE(*NEVER) or NEVEROPTIMIZE.
  • Provides improved performance for XML GENERATE.
  • Supports the debug encryption key compiler option, DBGENCKEY, to specify the key to be used to encrypt source code that is embedded in debug views of a module.

ILE C and C++ compilers

  • ILE C and C++ compilers support the debug encryption key compiler option, DBGENCKEY.
  • The ILE C++ compiler provides decimal floating-point support for ILE C++.
  • The ILE C++ compiler supports many of the C99 features defined in the ISO/IEC 9899:1999 C language standard.

Application Development Toolset

  • Provides Exit point QIBM_QSU_ALW_EDIT to monitor or disable changing source files using SEU, SDA, and RLU.
  • Supports SEU syntax checking at the 6.1 level for ILE RPG and ILE COBOL.

System Requirements

This page outlines system requirements for a server running IBM® Rational® Development Tools for i.


Operating systemSoftwareHardware
IBM i V7.1 The C and C++ compilers require the "System Openness Includes" (option 13 of 5770-SS1). Installing the "System Openness Includes" is optional for RPG and COBOL. The C++ compiler requires the Portable Application Solutions Environment or PASE (option 33 of 5770-SS1). To use the ixlc shell command, the Qshell interpreter (option 30 of
5770-SS1) must be installed.

Some components will need additional PTFs. The PTF information is available at:

www.ibm.com/software/awdtools/wds400/support/		 The following IBM i 7.1 Power processor-based servers and blades are supported:

  • POWER7: 8233-E8B, 9117-MMB, 9179-MHB, 8406-70Y, and 8406-71Y
  • POWER6 and POWER6+: 9407-M15, 9408-M25, 9409-M50, 8203-E4A, 8204-E8A, 8234-EMA, 8261-E4S, 9406-MMA, 9117-MMA, 9119-FHA, 7998-60X, 7998-61X, 7778-23X
  • POWER5 and POWER5+: 9405-520, 9407-515, 9406-520, 9406-525, 9406-550, 9406-570, and 9406-595
