COBOL for AIX enables you to selectively target code generation of your programs to either exploit POWER7® systems architecture or to be balanced among all supported POWER systems. The performance of COBOL for AIX applications is improved by means of an enhanced back-end optimizer. The back-end optimizer, a component common also to the IBM® XL compilers, lets your applications leverage the latest industry-leading optimization technology.
COBOL for AIX together with IBM Rational® Developer for Power Systems Software™ provides a productive and powerful development environment for building applications. COBOL for AIX includes a COBOL compiler, COBOL libraries, and a debugger. The debugger lets you visually debug programs wherever they’re running—as stand-alone jobs, in an SOA service, or as a CICS® transaction under TXSeries.
- Performance improvements in the COBOL runtime libraries that can help your applications run faster
- I/O performance for NAT (line sequential), RSD file system, STL (sequential) file system, and SdU (sequential and relative) is improved
- A new File System (RAW) allows direct access to a QSAM file transferred (using z/OS FTP) from z/OS to AIX
- A new WSCLEAR suboption that makes it easier to debug COBOL for AIX programs
