Relational Architects International (RAI) has announced Version 9.1 of its REXX Language eXtensions (RLX) product which lets users code SQL and XML statements, DB2 commands and IFI requests - all natively within programs written in the high-level REXX language, known as "REXX execs." RLX Version 9.1 fully supports DB2 for z/OS functionality at the
Version 9 level in traditional z/OS environments like TSO, ISPF and batch as well as in newer environments like System REXX, Health Checker, SDSF and ISPF panel exits.
In addition, RAI says that RLX Version 9.2 will fully support DB2 10 for z/OS (currrently in beta) when that IBM release becomes generally available.
RLX is compatible with the dynamic SQL syntax employed by DSNREXX and extends the IBM interface with full support for Large Objects and SQL/XML. RLX also supports the embedded SQL syntax used within compiled languages like COBOL, so developers can choose the syntax they prefer. The immediate execution and powerful debugging facilities provided by
REXX and RLX allows users to get started right away with pureXML and DB2 for z/OS, according to Carl Feinberg, director of development at RAI. REXX execs that combine SQL statements, XPath expressions, DB2 commands, IFI requests and RRSAF/CAF services can be developed rapidly and tested immediately without compile and link edit steps, and without preprocess and bind delays. "You can edit and test them directly within ISPF Edit, and get instant feedback," Feinberg explains.
Because there is no learning curve, says Feinberg, "z/OS developers can leverage their skills with REXX, SQL, XML and ISPF to become productive with pureXML and LOBs almost immediately." In addition to providing a way to learn and become familiar with pureXML in the DB2 for z/OS environment, RLX is also particularly well suited to quickly prototyping high volume systems, as well as develop tools, z/OS health checks and small applications - all with immediate feedback, extensive diagnostics and context sensitive help.
