Re: Handling Files in a Subproceedure

Maybe I worded it wrong. "Best Practice" maybe?

It looks like others do the same thing open and close the file on every
call. I didn't know if I could or should keep the file open while the main
program is running. This is in a module by the way.

Mike,

This may be too simplistic but I code an open and close procedure for
files I'm going to use. The first thing the application does is open the
files by calling the open procedure and the last thing is to close them by
calling the close procedure.

HTH,

Rick

Subject: Handling Files in a Subproceedure

We are adding application security (to hide some fields) to an application
of mine. I want to use a subproceedure to check for authorization. The
problem is that I have never really grasped the concept to how to properly
handle file opening and reading. I have always taken the easy way out and
just opened and closed the file every time the subprocedure was called. Is
there a sample somewhere on how to do this properly?
