Can you edit these fields somewhere in your application? If you can, it would be useful to use regular expressions to prevent users from entering strings in invalid formats. However, in my application the user is not allowed to enter values for "rate" or for "date", so there is no reason to use regular expressions.
8/ Borders are over fussy.
I don't have this problem because when the user wants to change a value, he presses a button and a update frame is openned.
All text values, and all fields (which are text only), contain only 8 bit characters, null terminated if less than the maximum length for the field. The character encoding is 8 bit US ASCII.
