| System Messages | 
System messages are defined using the PxPlus message library file *mlfile.xx (default: *mlfile.en). See *MLFILE.xx Message Library.
Error messages maintained in this file can be customized to support different languages using either of the following two methods:
| 
 | Method 1: | Use the DEF MSG directive to temporarily override the MSG( ) function. | 
| 
 | Method 2: | Create a copy of the *mlfile.en file and give it a different language extension such as de or fr. Then, use the *msgupd program to define the messages. |
