The content of S must not exceed 270F (9999 decimal).
The following diagram shows an example BCD-to-binary conversion.

In this example, N words of binary data is converted to BCD data.
If N = 3, the three words of binary starting from D00010 will be converted to
binary data one word at a time when CIO 00000 turns ON. The resulting BCD
data will be stored starting from D00100.
