Re: UC - User Controlled opens

[Larry Bolhuis <lbolhui@xxxxxxx>]

I strongly agree with John on this.  I have done this many times for the
same reason, that being that you may never need one or more files so why
bother opening them.

However, I posed this question to John Sears. He stated flatly that he'd
skip the required logic and let the system open them all at program
startup.  He said it was more efficient but did not go into detail as to
how or why.

Hmmmmmmmm.
