My impressions is that in Glenn's case "overchargesLevel1" is not

"overchargesLevel1" can be defined by the compiler only if the
definition of the other subfields comes from a file vs being
explicitly defined. Though I don't really ever see myself using this
- I am a -huge- fan of qualified files and reading into data
structures (vs a read implicitly loading a data structure).

Hi Kurt, you're right about "overchargesLevel1" not coming from a file.

Sorry, I didn't mean to suggest that "overchargesLevel1" can only be
defined if the overlaying subfields come from a file. I only meant that
if they _do_ come from a file, you don't have to code a data type in
free-form.

In both fixed-form and free-form, if an overlaying subfield (or any subfield) comes from a file, you can just code the subfield name without data type information, but you can can also explicitly define overlaying subfields.

f1,f2,f3 come from a file.

D ds ds
D level
D f1 overlay(level)
D f2 overlay(level:*next)
D something 10a overlay(level:*next)
D f3 overlay(level:*next)

dcl-ds ds;
level;
f1 overlay(level);
f2 overlay(level:*next);
something char(10) overlay(level:*next);
f3 overlay(level:*next);
end-ds;
