There's no "easy" way to display the entire record in one statement the way you can with a static "DISPLAY table-name" statement. You can get the count of fields (buffer-handle:NUM-FIELDS) and then step through the individual fields and display their values using
DO i = 1 to bh:NUM-FIELDS:
DISPLAY bh:BUFFER-FIELD(i):BUFFER-VALUE WITH DOWN.
DOWN.
END.
