Re: RPG-ILE Service Pgm and Opening/Closing Files

I'm thinking the 'file open' flag is superfluous. You'd open the needed file if "not %open(file_name)" is true. And you don't even have to test for %open before closing it, since the manual says you won't get an error if you attempt to close an already closed file.

Except if another procedure, in the same module, that called this procedure had opened the file before hand. If this is the case, and you close the file, you will end up with an ugly error.

The purpose of the flag is implement 'only close the file if we actually had to open it'.
