If the Compiler detects any errors, it does not create an object file. Rather, it creates an error listing file named err.txt. This file is generated in the directory where the source file was found (also see ERRORFILE: Error filename Specification).
If the Compiler's window is open, it displays the full path of all header files read. After successful compilation the number of code bytes generated and the number of global objects written to the object file are also displayed.
If the Compiler is started from an IDE (with '%f' given on the command line) or CodeWright (with '%b%e' given on the command line), this error file is not produced. Instead, it writes the error messages in a special format in a file called EDOUT using the Microsoft format by default. You may use the CodeWrights's Find Next Error command to display both the error positions and the error messages.
