Euphoria and fixed field record formats .....

I am new but have used Euphoria very happily and 
effectively for several projects and really like it.

I am interested in how those who have a depth of knowledge do code to
handle fixed format data records usually viewed as structures as in
Cobol, Basic etc. I processed  them in a CGI app using Euphoria by
just "slicing" every field from the record level "sequence"...but had
the luxury that all data was "text" or character.

But consider a tiny sample Cobol created record: 
                                       01  AAA.
        character      --->              03  BBB  pic x(12).  
        packed decimal --->              03  CCC  pic s9(5)  comp-3.
        zoned decimal  --->              03  DDD  pic s999   display.
        signed binary  --->              03  EEE  pic s999   comp.

This representative sequence often repeats in some pattern many times
per record.

What is the "right" way to address these values after one has read 
them into a sequence or object that is the result the I/O operation ?
