I am creating a conceptual adabas file using Predict 4.5. I have defined fields with numeric definition like below

```auto
> > + Fi: TEST-C L: 1 S: 3
     Ty L Field ID F Cs Length Occ D U DB S All
     *- - -------------------------------- *- * -------- ----- * * -- *
          1 TEST-1 N 4,0 *new*
          1 TEST-2 N 6,0 *new*
     SP 1 TEST-12 B 10,0 <edited

 DIC2501 FIELD ADDED SUCCESSFULLY.
 -- - -------------------------------- -- - -------- ----- - - -- -
```

When I try to create new fields combining full length of both the above listed fields with type as ‘Supervalue’ (SP) fields Predict automatically converts it to the Binary format.  
Is it something that we can not have numeric super descriptor or There is somting wrong the way i am doing?

Thanks,  
Puru

No, there is no such thing as a numeric superdescriptor.

> [@](#):

> The superdescriptor format is B (binary) if no element of the superdescriptor is derived from an A (alphanumeric) or W (wide-character) parent field; if any element of the superdescriptor is derived from an A or W parent field, the format of the superdescriptor reflects the last occurring A or W element; for example, if the last occurring A or W element is W, the format of the superdescriptor is W.
