Thank you, Aleksandar.

Yes, yes and yes.

This is what I was hoping to hear--that the logic is sound,but that 
there might be a problem in the construct. I've shied away from ( ) and 
{} in $ xxx statements because I'm really shaky on what they mean. I've 
also never seen the ' ' [ ] ' ' construct. I use the Advanced Bash 
Scripting Guide as my reference. Thank you for your feedback. I'll play 
with this.

I've done this with GDBM by adding `exit 1` at various points. The 
results are as I have described in my first post.

I appreciate your input. We'll see what happens.
