Cobol reserve word VS literal

Cobol reserve word VS literal

Cobol reserve word VS literal

While doing maintenance on cobol programs, I have been changing space literals ('  ') to the cobol reserve word SPACES.  Management has discouraged me from doing this.  Question:  Is there a significent benefit to use reserved words as opposed to literals?  

RE: Cobol reserve word VS literal

This really isn't an internationalization question...

But depending on how smart your COBOL compiler is, it may or may not be folding all those space literals into one variable.

I would create two versions of the same code -- one with the space literals, and one with the SPACES keyword (otherwise identical).  Compile them both and compare the size of the binaries to see if there's a significant difference.  It's also possible there's a difference in the runtime memory size -- ask your sysop for help.
