I have since found the 'value' function which seems to do just what is needed.
Thanks anyway!

Now for a more technical question.  I am writing an XCMD to copy resources from
one file (stack) to another, so that I can release a stack with a bunch of
'snd 's in it, and have it install them where you tell it.  I know there is
already one floating around, but this is mainly a learning exercise.
Well, it basically works, except when the target file does not yet have
a resource fork.

I am looking for this, and basically do the following:

	if ( (target = OpenResFile( targetFile )) == -1 )
	{	CreateResFile( targetFile );
		if ( ResError() != noErr )
		{
			return;
		}
		else if ( target = OpenResFile( targetFile ) == -1 )
		{
			return;
		}
	}

Well, the XCMD continues to function, but near completion, or immidiately
after returning to HyperCard, things go haywire.  Either the screen locks
up (usually), or pulling down menus to look at stack info causes HyperCard
to unexpectedly quit.  On occaision, my system will not reboot from my hard
disk, it just keeps trying, but when it get's to the desktop it instantly
returns to happy-Mac and tries again.  Replacing the system file fixes it.

In cases where the resource fork already exists it seems to work flawlessly
time after time.  Is there something I am missing about creating the
resource fork of the file?  I do later read the file looking for a conflicting
resource name before ever putting anything in it.  Tonight I am going to
try being a bit smarter about that.

Does this suggest anything to anyone?  I have very early versions of Inside
Mac.

Thanks for any help....
