Fred, John, et al.: > Does that help? Yes. Somewhat. And why not totally I don't -- yet -- understand. It does make sense that if characters are going to be grouped in the pattern part of the expression, then all characters need to be grouped. Including the single comma. Per John's suggestion I dropped the '.*' (intending multiple digits preceding the comma), yet not all instances of the pattern are substituted. The first lines of the input and output files show this.

Yet, in the middle of the second line (0,2 and 1,2.00) are not changed. In both cases the preceeding pattern is a single digit rather than 2 or more digits. Almost there!
