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

You've got a 303 byte data structure. It's overlaid by CollTxt, a 5 element
array (each element is 60 bytes). Positions 1-60 (and CollTxt(1)) is
overlaid with CollTxt1, and so on for 5 elements/fields. Then you have a 3
byte field (CollCode) at the end. So  you can manipulate the same memory by
acccessing data structure CollSO_DS, array CollTxt, or fields CollTxt1-5.
