I have been trading nearly 25 years and have a coding system for customers that involves the use of &, but I cannot incluse this in my customer code, why, SAGE which I have been using all that time allows for this? I really don'y want to have to change my system to shoehorn it into to Kashflow.
My system is simple, the first three characters of the name and a sequential numeric code - as soon as you start introducing exceptions simplicity is lost.
I would be happy to use + instead of & but I find it ridiculous in the extreme that a "cutting edge" system can't do what a DOS based one could do 30 years ago..
