Best Mainframe Application Development Software for IBM z/OS

Z/XDC offers developers an interactive and source-level debugging experience for mainframe programs within any z/OS environment, enabling them to navigate through live code, monitor variables in real-time, and address issues more swiftly than conventional techniques allow. By eliminating the guesswork inherent in traditional debugging, it grants comprehensive, real-time insight into program execution and introduces advanced debugging features to mainframe development. With Z/XDC, developers can significantly cut down on debugging durations, transforming a process that typically takes days into one that can be accomplished in hours, allowing them to test hypotheses instantly without the need for lengthy recompilation, make spontaneous modifications, run “what if” scenarios, correct problems, and validate solutions efficiently. Among its capabilities, Z/XDC allows for precise line-by-line stepping through code, instant code alterations, flag adjustments, modifications of data fields and registers, control over the Program Status Word (PSW), and the ability to load or delete modules, as well as manage memory with GETMAINs and FREEMAINs, and post Event Control Blocks. Additionally, it ensures source-level visibility, allowing developers to view the code as initially written, automatically load source image maps from ADATA, and access a variety of other helpful features, making it an indispensable tool for modern mainframe programming. This integration of advanced debugging functionalities enhances overall productivity and streamlines the development workflow for programmers working in mainframe environments.

SQL-Ease for Db2 for z/OS significantly accelerates the processes of application review, debugging, and SQL performance optimization without requiring a departure from the ISPF edit environment. This tool effectively shortens development timelines by enabling developers to test and refine their SQL queries prior to the compilation of the program. Programmers can seamlessly test, debug, and optimize embedded SQL directly within the ISPF editor, utilizing various functions for generating, standardizing, checking, executing, interpreting, and analyzing SQL commands. SQL-Ease is capable of producing syntactically accurate SQL statements, including SELECT, UPDATE, DELETE, INSERT, MERGE, JOIN, UNION, and subselect queries, for languages such as COBOL, Assembler, SPUFI, PL/I, and C, and integrates the SQL into the designated location within the code. Additionally, it can transform manually written SQL into a uniform, easily comprehensible format, verify the syntax of SQL queries, execute SQL from both application programs and the SQL Editor, while also returning results accompanied by crucial execution metrics that aid in further performance tuning. Ultimately, SQL-Ease serves as an indispensable tool for developers looking to enhance their workflow while ensuring high-quality SQL performance.
