hello!
i have a database file with "dat" extension. it seems to be a b-tree structure db file. i have just got the data and the metadata. i am having problems interpreting length of its fields. becuase the meta data file contains these kind of length description in length box.

len1,2 Type FieldName
.................................................. ......................

7,0 INT EMp_ID
6,3 String Acc_Desc
6,1 INT Entry_Last


now i dont know, what does this length 1, 2 mean. its not padding nor something to do with decimal places ofcourse. its always length 2 with string, and 1 or 0 for INT. Total Length of all the fields include both length1 and 2. advanced thnkx for helping me out.
