Syntax:

ferr() | ferr!()

The FERR() function returns error information subsequent to the last LOAD or SAVE statement. The function can return a byte or an integer.

If the return value is zero, no error occurred. Otherwise the value will hold the matching KERNAL error code.

Example:

load "myfile",8
err = ferr()
if err = 0 then print "success" else goto load_error
end
load_error:
	print "an error occurred"
	rem ** more error handling **
