Debugging of LISP Functions in ARES

Since XtraTools have been included, the debugging of user LISP routines is blocked. The XtraTools contain protect lisp files, this lead to a general protection of LISP and all debugging functions don't prompt anything to the command line window anymore.

The easiest way to debug LISP in ARES Commander, you rename the C:\Program Files\Graebert GmbH\ARES Commander 2019\XtraTools\ temporarily to e.g.
C:\Program Files\Graebert GmbH\ARES Commander 2019\_XtraTools\ and restart the ARES again.

Then you get an error message at the startup:
Loading main.lsp... OK.
Loading LoadXtraTools.lsp... Error: Folder "XtraTools" not found!

Now you can use the tracing command below to debug LISP:

(*settrace* variant [seconds])

The *settrace* function sets the mode for tracing of Lisp routines and functions.

The integer value variant may be combined (as follows):

0 No trace
1 Display allocated memory
8 Display function that caused an error
16 Display in case of an error all expressions up to function that caused the error
32 Display any Lisp expression evaluated
32+64 Display any Lisp expression evaluated (each line of code) needs to be confirmed by pressing any key
32+128 Display any Lisp expression evaluated. Halts at the end of a line for a certain time specified by the argument seconds. The default value is 5 seconds.

Note: As soon as protected Lisp files are loaded, the *settrace* function does not work (by intention). When writing your own programs or when porting you should avoid loading protected Lisp files.
