You use this function to perform static checks that are too time-consuming for the normal syntax check. The extended program check returns both errors and warnings. It is possible to run either individual specialized tests or one whole standard check.
The system displays a list of possible check options. By default, all of them are selected. For detailed information about a particular option, position the cursor on it and choose F1.
For each option you have selected, the system displays an overview of the number of errors, warnings, and messages.
From that screen you can jump to the appropriate point in the program and correct the error.
