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. ?
You may find something close to what you are asking for by using DDUTILTY:
For example, for our Table PERSON:
//SYSIN DD *
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.
Language ALC will give you the assembler equivalent.
More like the DSECT you were asking.
