Is there anything wrong in using an unstored calculation field within another calculation?

I have a database that is used to print barcoded container labels. In this database, I have a quantity field and an external function that uses a calculation field to create the barcode. One of my customers requires leading zeros for the quantity field. To accommodate this requirement, I created a calculation field, qty_8_chr, that is an unstored calculation:

Right ("0000000" & qty;8)

The barcode calculation is Barcode(qty_8_chr,1,0,1)

It seems to work properly, however, I wasn't sure if this is good practice?

Any advice?

If that's the only thing it's needed for, why not make the barcode calculation =

Barcode ( Right ( "0000000" & qty ; 8 ) ; 1 ; 0 ; 1 )

and eliminate the field?

Well, I need a "human readable" portion above the barcode, so I need a text field to display "0000018". My current qty field only displays "18".
