A flag variable designed to indicate to the system what action ought to be taken if an error of severity greater than 0 is met during certain file io operations. If this variable is set to 1 these errors are passed back to the program performing the io operation to deal with. If set to 0 the system will handle these errors automatically. This can be used to advantage when errors are expected and the program wished to deal with them direct rather than have the system interrupt. For further information see p49 of the Advanced Revelation 2.0 Quick Reference Guide. Can be amended.
