I presume by "unchanged" you mean the attribute associated with the  
field is not in effect? That is the field is not HIghlighted and  
ReverseImaged and the cursor is not placed in that field.

Yes. PUTOVR works in conjunction with OVRATR and OVRDTA. You answer  
is in the Information Centre:

"The following conditions cause the Put-Override keywords to be  
ignored and no error to occur:
PUTOVR is not in effect at the time of the output operation.
Neither the OVRDTA nor OVRATR keyword is in effect at the time of the  
output operation.
The record format is not already on the display."
