Aside from error reporting, there are some techniques that can be used for system verification:

• Finding graphics links made by tag index instead of tag name
• Using WinMerge to compare build reports
• Using Config Parser
• Occasionally DBDOC_SUMMARY.ERR contains messages like

sqlite_step_exception in "E:\Project\EXPORTS\master.db" with 8,160,10,1620:  
Step 11: database disk image is malformed

or

exportlookup.reset() returns 11 for E:\project\EXPORTS\master.db.

These messages are temporary, caused by changes in the structure of the master.db file, and after rebuilding the project, they are expected to disappear. For more information contact GMCL.
