You can use the following utilities and system commands to gather information on codefile verification data.

FILEDATA Utility

The FILEDATA utility provides an option to report if the codefile has a valid checksum. Running FILEDATA with the CODEVERIFICATION request specified displays the checksums stored in each codefile when a checksum is present. The output displays if the checksum is not valid, allowing you to verify if individual or multiple codefiles in a directory include a valid checksum.

See the System Software Utilities Operations Reference Manual for more information on using the FILEDATA utility.

FILES and LFILES CANDE Commands

The CANDE LFILES command invokes the FILEDATA utility to display the file attributes, including codefile verification data when present.

The FILES command including the SHOW expression uses the ASERIES_INFO programmatic interface to retrieve and display the checksum attribute.

PD, PDIR, and PDRES System Commands

The PD (Print Directory), PDIR (Process Directory), and PDRES (Print Directory Resident Files) system commands display various attributes for an individual file, including codefile verification data when present.

See the System Commands Reference for more information on using these commands.

DO System Command

The DO (Diagnostic Options) system command includes a SIG option which, when set, writes diagnostic information for each codefile. This diagnostic information can be used to troubleshoot errors encountered by the codefile verification process.

See the System Commands Reference for more information on using this command.
