Reference Manual > Files

A log file is a file that records events as a program proceeds. It will normally be a text file (.txt) or a simple spreadsheet (.csv) file.

When the preprocessor is run a text log file with the same name as the CL script file followed by "Log" will be produced.

For example, a tables run called "Extra run.qtf" will produce a log file called "Extra run Log.txt".

If the preprocessor succeeds this same log file will also be used by CL.

If the preprocessor fails this will contain a lot of information about where the problem occurred and the values of all the indices when it failed:

•The exact position where the error occurred

•The exact position where any current *INSERT commands were called

•The exact position where any current cell references were used

•The last few characters parsed

•The exact position that a command was entered last

•The exact position of the last command started if the commands are nested

•The loop counter for any open loops

•All index names showing type and current contents
