MetaData (size of datatype)

Hi tom,

how to decode the atttypmod field........when i allocate 10 it shows it as 14 
n for 20 it shows it as 24.......my problem is not just with 
varchar........it is for all fields that has variable length .........the 
same atttypmod returns -1 for integer? am confused........

I want the size allocated for each field i a table whether its a var-length 
or fixed length........
