When the file is first opened, the cursor is positioned on the first line that contains errors. Every error message follows the line to which it refers. After the current error line is a reference to the next error, or the string last error meaning all errors have been found. Once the corrections have been made, the editor should be exited normally. mcc strips the error messages from the source and re-invokes the compiler for another try.

This process continues until the program is free of syntax errors. The edit/compile cycle can be broken by leaving the editor without making changes, or by using a keyboard interrupt to terminate mcc after having left the editor.
