XINFO Source Scanner XINFO’s source scanner are analysing program source code to deliver the following information: • General Info: Basic information like “uses static SQL”, “uses dynamic SQL”, “calls CICS” • Includes: Usage of includes and copy members • Calls: External program calls (tables and graphics) • Files: Access type (e. g. read/write) and definition (file names, record length etc. ) • DB 2: Which program uses which tables (select, insert, delete, etc. ), and columns • CICS and DLI: Calls and their parameters • Variables: Definitions and usage • Comments HORIZONT 26 XINFO – How to use XINFO in Development
XINFO Source Scanner Following data can be input to the source scanners: • PDS/PDSE • Librarian • Source path (Java) • Compile listings • Selection: - Complete libraries (Source plus include/copy) - Specific members specified by name patterns (include/exclude) • Full scans or incremental updates, e. g. all changed programs HORIZONT 27 XINFO – How to use XINFO in Development
XINFO Program Calls In addition to language specific data (COPY, variables) XINFO offers “multi language call analysis” • Input are the results of the individual scanners • The results are three tables (Calls, File- and DB 2 -Access) - Including nested calls Program A calls B, B calls C, as a result A calls C on level 2 - Language independent No matter if A is COBOL and B is ASM - Supports development “staging” Test program may call production module, but not vice versa HORIZONT 28 XINFO – How to use XINFO in Development
