After assembly, there are several ways to check where different errors or warnings have been detected. The default format of the error message is as shown in the following listing.
Default configuration of an error message >> <FileName>, line <line number>, col <column number>, pos <absolute position in file> <Portion of code generating the problem> <message class><message number>: <Message string>
