This menu command is used to commence analysis of the network. The data is first checked for consistency and, if it is found to be sound, the network can be analysed and the analysis engine is invoked. Otherwise a window showing all the data inconsistency errors is displayed. The errors and warnings shown may be re-displayed by selecting the Show Errors menu command.

The mandatory consistency checks performed at this stage generally concern relationships between data items, and are outlined in more detail in the XP System Capabilities section.

If no errors or warnings are detected, no error log is generated, It will now be possible to analyse the network.

When Solve is clicked, the analysis engine is loaded.  Once the analysis is complete, any errors or warnings encountered are reported. The system will automatically create a .out file with the same name as the database file.
