I was thinking about this. If a record is added and the field is left  
empty does it still take up the disk space?

Please tell me if the following assumptions are correct:

Example Record we will call it "TESTREC":
field1 is a VarChar Field and has a length set to 400 but only has 50  
chars used <<< this takes up 400 chars worth of disk space
field2 is a VarChar Field and has a length set to 700 and all 700  
chars are used <<< this takes up 700 chars worth of disk space
field3 is a TEXT and uses 4000 chars <<< this takes up 4000 chars  
worth of disk space

so "TESTREC" uses 5100 chars worth of disk space

Is this correct?


Thanks,

Joseph
