When trying to dynamically set the USING fields of BUFFER-COMPARE, I get the following error.

WARNING: The USING phrase of the BUFFER-COMPARE statement only honors fields in the source buffer. Ignoring 'cFieldsToCompare'. (5379)
Here is a code sample to clarify, I would like to only compare Field1, Field2, Field4 between buf_target and buf_origin. However, I can't simply write the fields down because they are provided and won't always be the same.

DEFINE VARIABLE cChangedFields AS CHARACTER NO-UNDO.
DEFINE VARIABLE cFieldsToCompare AS CHARACTER NO-UNDO.

cFieldsToCompare = "Field1,Field2,Field4"

BUFFER-COMPARE buf_target
USING cFieldsToCompare
TO buf_origin
SAVE RESULT IN cChangedFields NO-ERROR.


Is there a syntaxe that allow BUFFER-COMPARE to receive fields to compare dynamically?
