 645 /*---------------------------------------------------------------------------
 646  * Set of debugging macros used by the libraries. If the debug flag is
 647  * set, they are turned on depending on the setting of the flag. User code
 648  * can override the default functions called when a check fails, and the
 649  * MGL does this so it can restore the system from graphics mode to display
 650  * an error message. These functions also log information to the
 651  * scitech.log file in the root directory of the hard drive when problems
 652  * show up.
 653  *
 654  * If you set the value of CHECKED to be 2, it will also enable code to
 655  * insert hard coded debugger interrupt into the source code at the line of
 656  * code where the check fail. This is useful if you run the code under a
 657  * debugger as it will break inside the debugger before exiting with a
 658  * failure condition.
 659  *
 660  * Also for code compiled to run under Windows, we also call the
 661  * OutputDebugString function to send the message to the system debugger
 662  * such as Soft-ICE or WDEB386. Hence if you get any non-fatal warnings you
 663  * will see those on the debugger terminal as well as in the log file.
