LUX can offer you a helping hand in trying to find out where the mistakes are in your programs. The process of finding and removing errors is called debugging, because in the very early days of computers computer program failure was sometimes due to the presence of insects (commonly referred to as "bugs") in the computer.
For figuring out where something went wrong, LUX offers several kinds of help, as listed below.
|• Error Messages:||What you see if something goes wrong|
|• Variable Inspection:||How to check the values of variables|
|• System Inspection:||How to check the condition of LUX’s innards|
|• Tracing:||How to trace execution of your commands|
|• Stepping:||How to step through execution|
|• Help Routines:||How to find information about routines|
|• Diagnostic Output:||How to record input/output to a file|
