Tim,

Because you don't specify a length for SomeDs, its length is calculated to
12, based on the fields you specify.  So when you point SomeDs to *In, it
contains indicators 01 to 12, including some you did not specify.  Initially
its value is '000000000000' (12 times *OFF).  When you seton indicator 02,
SomeDs contains '010000000000'.  When you use the debugger, it will only
show you the subfields you have defined, so you will not see the '1' in
position 2.

But why are you comparing a data structure to *OFF?  According to the
documentation *ON is all ones and *OFF is all zeros, so after you set on
*IN02, SomeDs is neither *ON nor *OFF.
