Hi,
I would like to move a reference variable to the content of another variable. Is this possible?
Let see an example:
DECLARE ref REFERENCE TO OutputRoot.XML
SET OutputRoot = InputRoot;
SET Environment.Field = 'FieldA';
I need the referencie to point to OutputRoot.XML.FieldA, So I tried
EVAL ('MOVE ref TO ref' || Environment.Field)
but it doesn´t work, any idea?
thanks

Lillo,
You cannot reference to something which doesn't exist! In your code you are trying to create a reference to some field in Output tree but your output tree is created below it.
You should rearrange your statements as follows,
| Code: |
SET OutputRoot = InputRoot;
DECLARE ref REFERENCE TO OutputRoot.XML
SET Environment.Field = 'FieldA';
EVAL ('MOVE ref TO ref.' || Environment.Field)
|
Remember, EVAL is an expensive operation. You can implement the same using Reference Variable and MOVE, LASTMOVE, FIELDNAME, ..
Regards,

Thanks for your reply, but what is more expensive use the eval function or search for different tags in the xml tree using the reference?
Thanks in advance
