Question:
However I would like to know more about the offsets of the various fields in that Table PERSON  and other tables and I believe a DSECT would provide that information. Perhaps you know of another way to get this type of information. ?
Answer:
You may find something close to what you are asking for by using DDUTILTY: 
https://docops.ca.com/ca-datacom/15-1/en/using/ca-datacom-datadictionary-batch-facilities/ddutilty-producing-reports-and-source-language-statements/ddutilty-sample-job-streams-and-output 

For example, for our Table PERSON: 
//SYSIN DD * 
+USR DATACOM-INSTALL,NEWUSER 
-UTL LIBRARY,OS 
-UTL LANGUAGE,COBOL,DESCRIPTION 
-UTL COPY,TABLE,PERSON(PROD),PER-TBL 
-END 

However the above does not give the offsets. But gives a full copybook layout. 
Replace DESCRIPTION by NONE to get a easier output to read, 

But using DR instead of COBOL will give the offsets. 
Offset starting at 301, see docops for further information. 
Several language are supported. 
Additional Information:
Language ALC will give you the assembler equivalent. 
More like the DSECT you were asking.
