Powerful File Comparison

Comparex is the only mainframe comparison tool that supports data, text, and directory files in a single product. Available on z/OS, z/VM, and z/VSE platforms, Comparex is accessible via both ISPF and batch interfaces.



Data Comparisons

Comparex compares complete data records or individual fields and can display differences down to the byte or half-byte level. Data fields of various types can be compared, with automatic conversion between formats. Comparex compares dates fields in files whether they have two digit years, four digit years or a mixture. Dates can be alpha-numeric and be compared successfully.

Text Comparisons

Comparex finds and isolates differences in text files and highlights them in an easy-to-scan delta report. Comparex supports a wide range of file types, including ADABAS, DB2, IMS, CA-DATACOM, FOCUS, CA-IDMS, Oracle, Wylbur, CA-Librarian, CA-Panvalet, JCL, COBOL, PL/1, FORTRAN, CLIST, REXX, HTML, XML, reports and documentation files.

Directory Comparisons

When you only need to compare directories for member names, Comparex has you covered. It supports directory member comparisons on PDS or PDS/E libraries.

Copybook Parsing

If you are doing a DATA comparison and the files to be compared have a COBOL, Assembler, PL/I or DCLGEN copybook layout associated with them, Comparex provides a parser that can produce an accurate keyword layout which can be imported to your comparison routine.

Delta Decks

The differences detected during a comparison can be written to a separate file called a delta (change) deck. Comparex allows users to create delta decks in CA-PANVALET, CA-LIBRARIAN, IEBUPDTE or ChangeMan ZMF format.

Flexible Reporting

There are over 50 options in Comparex for report formatting, including alphanumeric and hexadecimal display.
