Bob Rose, or someone at group, please:
I have copied byte order info., (please see below) that I entered at window # 3 
in CatGen 1.3 (please note I added zeros as Cat Gen did not anticipate more 
bytes further along into catalog.  

                1               2                3                4             
   5               6                7                8

0000  000 000  000 000 
 
I find 20 fields and have entered 20 fields, but every time get error message, 
i.e. <Required Field Missing!>
Please explain where I have gone wrong?

I hope everything lines up in posting!
The catalog referred to is <CDS I/90  Positions of 502 Stars in Pleiades Region 
(Eichhorn+ 1970)>
