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 **
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) |
