753.0. "Encoding Seq's of Records" by LEVERS::CIARFELLA (Saabless and happy) Tue Feb 26 1991 18:40

This is a related question to note 206 but since it deals with SEQUENCES 
of records I thought it would be best to start a new entry.

In my AM I'm trying to encode an attribute which is a sequence of records.  
I'm not sure what the ILV ids should be for each record entry and the fields 
within each record.  My latest attempt is presented below.  

Am I close or am I meandering around Robin Hood's barn?  Specifically, am
I correctly identifying each instance of the DevConfigType record and,
likewise, each field with the record?

 TYPE
    DevConfigType = 1090 RECORD
	FRU Type     = 1 : FruType ;
	FRU State    = 2 : FruStateType ;
	FRU ID       = 3 : FruIDType;
	FRU Revision = 4 : FruRevisionType ;
        END;

 TYPE
    DeviceConfigurationType = 1091 SEQUENCE DevConfigType;


	ATTRIBUTE Device Configuration = 43 : DeviceConfigurationType
		ACCESS = NONSETABLE, 
		DISPLAY = TRUE, 
		SYMBOL = CONC_DEVICE_CONFIGURATION,
		CATEGORIES = (CONFIGURATION)
                (* PRIVATE
                   NATIVE_CODE = %X'0026 829F',
                   END PRIVATE *)
		(* Description: the device configuration	*)
	END ATTRIBUTE Device Configuration;

The ILV dump is as follows:

                )

    Hello there,
    
    In MCC, our support of the SEQUENCE datatype does not allow its
    basetypes to be repeated.  In other words, in your datatype of
    SEQUENCE of RECORD, you can only encode a single record.  Will
    the SEQUENCE OF datatype work for you instead since you only have
    a single basetype?
    
    Assuming that you do switch to using SEQUENCE OF, your IDs for each
    element of the SequenceOf need to be 1's only, and not incremented
    for each element.  Your Record field IDs are correct.

    Thanks, Christine.  I used SEQUENCE OF and now it works great.
