This section describes the parameters that can be specified for a function in the input fields of the SYSERR main menu. Any restrictions that apply to the use of parameters with a particular function are described in the section Functions.
Message type specifies the type of message to be processed. The table below lists the message types available:
| Type | Explanation | 
|---|---|
| NS | Natural system short messages | 
| NL | Natural system long messages | 
| US | User-defined short messages | 
| UL | User-defined long messages | 
Library specifies the library for which
                  			 messages are to be created or maintained. The specification of a library is not
                  			 required when accessing Natural system messages (Message
                     			 types NS and NL); any input values in the
                  			 Library field are ignored.
               
Message number specifies the first and last number of a message range. The maximum message number for a library and language is 9999. The message number 0000 is not allowed. To specify only one message number, either enter the number of the message in the left Message number field and clear the right field, or enter the number in both fields.
Language codes specifies a maximum of 9 from 60
                  			 language codes available. The language codes are single alphanumeric characters
                  			 in the ranges 1 - 9, A - Z and a - y. To view or select language codes, enter a
                  			 question mark (?) in the first position of the Language
                     			 codes field and press ENTER. For more information, see
                  			 the system variable *LANGUAGE
                  			 in the System Variables documentation.
