RE: This is confusing me. What are these lines of code doing?

It's been awhile since I ran the CVTRPGSRC command, but wouldn't that
command have converted an RPGIII multiple occurrence DS and made it come out
like Booth's example?

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)
