It looks like when given a number, this program outputs a description of that number. For example, the number 664555 could be described as "2 sixes, 1 four, 3 fives" which would be represented on the calculator as 261435. Apparently, the original program had trouble with long numbers, so he's splitting the output into a "double deck" (two rows) with the number of times each digit appears being written above the digit. So, the output 261435 would look like:
213
645

Now, if your question is why anyone would want to do this, I don't know. Maybe it has something to do with number theory? It reminded me of a programming class about 40 years ago where we had to convert a number to written text. For example, if the input were 3164, the output would be "Three Thousand One Hundred Sixty Four". This was used by banks and other businesses to write checks.
