Would we have the same results if the code had been:
 D CollSO_DS       DS
 D CollTxt                       60    DIM(5)
 D CollCode

and used CollTxt(n) instead of CollTxt1 through CollTxt5?

What makes this confusing, I think, is that it used "from - to" to define the fields' positions instead of lengths and the overlay keyword.

I would have coded it like this:

D CollSO_DS       DS
D CollCode                       3
D  CollTxt1                     60
D  CollTxt2                     60
D  CollTxt3                     60
D  CollTxt4                     60
D  CollTxt5                     60
D  CollTxt                      60    DIM(5) overlay(CollSO_DS:4)

D  CollTxt2              61    120
D  CollTxt3             121    180
D  CollTxt4             181    240
D  CollTxt5             241    300
D CollCode              301    303

This is confusing me.  What are these lines of code doing?  How long is
the data structure CollSO?  What happens if I increase the DIM from 5 to 10?
