What happens if something goes wrong?

First, check that your inputs are correct. You can get help from the Tool Manager window by left-clicking on the Help button and choosing the Reference Manual option. This will drive your browser to the AIPS++ detailed documentation on each tool. From this web page, you can also reach the main AIPS++ documentation site (left-click on Documentation in the upper left of the web page) or you can run a Search on key words you are interested in.

If your inputs are correct and you are still having problems, you may have discovered a software bug. If you find a bug during your data reduction session, type at the Glish command line prompt:

                bug()

Or, using the Tool Manager Help button, choose Report a bug option. This will bring up a bug report GUI (Fig. 1.3) that you can fill in and submit automatically within AIPS++.

**Figure 1.3:** *AIPS++* bug report GUI. Fill in the blanks and left-click on the **Submit** button. Your report will be sent to the *AIPS++* project team and you will be sent e-mail giving you the status of this problem or enhancement request.

If something has gone wrong and you want to force an exit, type a 'Control-C' in the Glish window. Glish will ask you 'exit glish (y/n)?' Answer yes by typing 'y.' Save this technique for emergencies.

If you manage to find yourself in a hung state (don't worry, this is rare), you can always kill AIPS++ from a LINIX or UNIX command line with:

       LINUX:   ps -aux | grep aips++
        UNIX:   ps -aef | grep aips++

    Note the process ID numbers listed and kill them with the command:

                kill -9 process_id
