This option specifies the maximum number of errors allowed before compilation stops. It indicates the maximum number of error-level or fatal-level compiler errors allowed for a file specified on the command line.

If the maximum number of errors is reached, a warning message is issued and the next file (if any) on the command line is compiled.
