keeping blanks out of the data

This is probably a dumb question but I don't have an sql/preform manual for this information. I am using the standard engine and would like to know if there is a way for me to keep the blanks at the end of a form from being saved (attribute). The user likes to space bar for deletion of mistakes rather then using ^d. I would also like to know if there is an easy way to remove existing blanks from the end of fields in the database or set fields with only blanks to a null. Any help is appreciated.
