The specific debug settings listed below will each output a particular type of diagnostic information, when included as the diagnostic type parameter of the set debug command:

To produce diagnostic data for all of these functional areas, write the diagnostic types as a range, i.e. set debug=10.25-27,=filename.

To request only certain types of data in the output, which are not necessarily consecutive in number order, separate the entries with a comma. For example, the command set debug=10.25,10.27,=filename will output context matching and generated text processing speeds.

If you have narrowed down the problem to a specific functional area and are trying out fixes, you can reduce the number of lines of diagnostic output to a single type by using a specific debug setting. For example, the command set debug=10.27,=filename will output data relating to the processing of generated text only.
