when you use the diamond operator (<>) for I/O, and you haven't.
So, having defined $^I and set @ARGV, you then need a loop:
while (<>) {
# Do something with $_
# print something to default filehandle
}
Whatever you print to the default filehandle inside that loop will
go to the new file.

That's twice now. I'm disinclined to help since I will doubt that whatever
you post is what's really giving you the problem, because you evidently
don't want to show us the real code.

Why don't you post the actual code since this obviously isn't it...

Can anyone tell me what the Perl driver for MSAccess is called and how to

You are looking for the TK module for Perl. Perl/TK allows you to
create windows and everything that goes along with them.

x27;R' command works by storing that information in environment variables.
You could hack it to save the information in a file as well, and look for
that file on startup.

Reasonable for short files, wastes memory for big ones. This file
opening looks like too much work. I prefer:
{
local @ARGV = "/location/of/header.incl";
print while <>;
}

other way I see doing this is to write each section of code as a subroutine
within the daemon program and have that called. Any suggestions on which of
these would be better? More correct? Etc.?
Thanks in advance for the help yet again.

eletes the file afterwards. If
there are no files, then the "daemon" simply sleeps for 30 seconds before
looking again. This seems like a very simple way of attacking the issue.
Any ideas fore or against?

As a way of testing its effect on a lot of scripts you have
certainly found an effective way. I would hesitate to put it into
production unless the module was called something like
Foo::Bar::GloballyUnbuffered, or at least its documentation said at the
beginning, "*** WARNING, THIS MODULE SETS $| ***"
This sort of action at a distance is generally considered an unfriendly
interface. I believe in leaving the setting of variables like $| to the
calling program. But if you know what you're doing, have at it.

What's the simple Perl command to find the name of the file from which the
Perl program is being executed? It was recently on this newsgroup but I
can't find the article now.
Thanks,

follows in the piece of code that calls the modules that produces the error:
use Date::Calc qw(Add_Delta_Days);
Does anyone have an idea?? And thanks in advance.
