varchar is a variable length character field, meaning varchar(20) will support UP TO MAX of 20 chars, but will store less if your data has less. A char(20) field always stores 20 characters, regardless if your data doesn't fill up the 20 characters. So it's a matter of simply saving space on each record based on the size of your character data. Seek, locate, select sql all work the same for char & varchar fields. The varchar came from SQL Server and was added to Foxpro later on to support moving data between the two.
