It was subsequently acquired by Computer Associates . Products Optimizer Capex s IBM COBOL Compiler Compiler optimization optimizer using Peephole optimization This product had two significant additional components The first was called Analyzer, and the second was called Detector. The former allowed execution analysis giving a count of the number of times instructions were executed. This provided a way for the programmer to move code so that the most often executed conditions would be found first, thus saving time on needless IF statements. While this may not be significant for a few hundred input file records, it was very important when there were millions of input records. The latter, Detector, trapped execution abends , or abnormal ends to the execution of an instruction, displayed the contents of applicable fields, and could be told to apply a fix to the offending field so execution could continue. The programmer could then correct one or more error conditions later and recompile the program. Both were substantial time savers in mainframe OS MVS and DOS VSE COBOL environments.

Interlink was founded in 1983 by Lambert Onuma and Greg Thompson, formerly of Digital Equipment Corporation . The company s first product, called simply Interlink , allowed IBM mainframes to be connected to VAX computers on a DECnet network. In 1990, Interlink acquired a product called ACCES MVS from Advanced Computer Communications , which implemented a native TCP IP protocol stack on the MVS operating system. First released in 1986, ACCES MVS had been the first commercial TCP IP implementation for MVS mainframes. Interlink developed and marketed this product as SNS TCPaccess . The prefix was later dropped, and TCPaccess became the company s main focus of development by the mid 1990s. Meanwhile, in 1989, IBM had introduced its own TCP IP offering on MVS. This product had been Porting ported from the VM operating system VM operating system, and required expensive and inefficient protocol conversions. Interlink was able to successfully sell TCPaccess as a more efficient and better performing alternative, and as late as 1996 it still held 25 of the TCP IP market on MVS. As the decade progressed, IBM improved its product, and Interlink s market share steadily eroded. In August 1996, Interlink became a public corporation, with an initial offering of 10 per share on the NASDAQ exchange. In December of that year, a strategic agreement was announced with Cisco Systems to jointly develop and market the TCPaccess product as Cisco IOS for S 390 . Share ... more details

UNIX System Services USS is a required, included software componentry component of z OS . USS is a certified Unix UNIX implementation XPG4 UNIX 95 optimized for mainframe architecture. It is the first UNIX 95 to not be derived from the AT&T source code. Through integration with the rest of z OS, additional Time Sharing Option TSO commands are available alongside the usual UNIX services, making it possible to process UNIX files using ISPF . Extensions in Job Control Language JCL make it possible to use these files in batch processing . UNIX System Services allows UNIX applications from other platforms to run on IBM mainframe s. In many cases only a recompile is necessary, although additional effort may be advisable for z OS integration such as SMP E installation support . Binary programs using hardcoded ASCII numerical values may need adjustment &mdash z OS users often prefer or require EBCDIC support. Programs running under USS have full, secure access to the internal functions of z OS. Database access IBM DB2 DB2 via Call Attach is one example of how USS can access services found elsewhere in z OS . Naturally such programs cannot be ported to non mainframe platforms without rewriting if they use these z OS specific services. Conversely, if a program adheres to standards such as POSIX and ANSI C , it will be easier to port to the USS environment. The file systems for USS the older Hierarchical File System IBM MVS HFS and the now preferred ZFS IBM file system zFS , which support UNIX style long filename s, appear as special VSAM Data set IBM mainframe dataset s to the rest of z OS . Numerous core System z subsystems and applications rely on UNIX System Services, including Java programming language Java . USS also provides a Shell computing shell environment, OMVS. USS s predecessor was an operating system component called OpenEdition MVS , first implemented in MVS ESA 4.3 and enhanced in MVS ESA 5.1. OpenEdition MVS only supported the POSIX standards.
