Hi,

Thank you for your reply.  I will run the program that you 
mention and see what happens.  

Please be aware that I am doing this for my own good more than 
for my mom's business.  The DOS based billing application that 
she uses is very old and she wants something new.  The only 
thing she does on that application is end of the month billing 
and she keeps track of the total amount billed during the year.  
She does everything else on paper as she hates computers.

She wants to have a new program by January and I offered to see 
if I could write one by then.  She wants something that will be 
tailored exactly to her business (a dental lab).  If I can't 
get it to work in time or the program I write is unsuitible, she 
won't use it and buy a professional application, it's as simple 
as that.  I know that by no means will the program be as feature 
rich as a professional ver., but she wants something very simple 
and she wants it to work just like the DOS program she uses now.

As I mentioned, I am a first year programming student and I 
think it would be a great learning experience for me.

Thanks again for your input,
Joe
