====== FERR() ======

Syntax:

  ferr() | ferr!()

The ''FERR()'' function returns error information subsequent to the last ''[[LOAD|LOAD]]'' or ''[[SAVE|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 **

Example error codes:

^ Code     ^ Error ^
|4|file not found|
|5|device not present|
|8|missing file name|
|9|illegal device number|
|29|load error|
|30|break (user pressed break button)|
