OVRDBF without any parameters specified

Can we specify an overide statement without actually specifying any parameters to be overridden.

In one of the exisiting codes (in a CL)I saw a line as follows:

OVRDBF             File(ZFT00981)     ToFile(ZFT00981)

No parameters were specified. The file name is exactly same.

The program is being used since ages. Hence I know this will not result in any runtime error.

But will this command have any affect on the file access or any affect in the program?

I think it will not have any affect. I think it will not make any difference anywhere even if we remove this line.

Please comment.
