-NO mcompile option
The -NO option that can be used with the mcompile utility command.
The no overwrite (-NO) option of the mcompile utility command is used to indicate that an existing compiled map file (.mmc) is not to be overwritten. If the no overwrite (-NO) option is specified in the command line of the mcompile utility command, and a file with the same name as the resulting compiled map file exists, it will not be overwritten, the map compilation will fail, and the Compilation error - The compiled map file cannot be overwritten, file already exists message will be written to the mcompile log file, if enabled. If the (-NO) option is not specified, the file with the same name as the compiled map file resulting from the compilation process will be overwritten.
