Take a look at the DFSORT manual available in this site.

As per the above sort card you are updating the 100th byte in the output file with the character "1". |

By BUILD you are building your output record. Here in the output record you will have
1,10 -> first 10 bytes from input starting from pos 1 in the output.
101:1,10 -> Again in the 101st byte you will have the first 10 bytes of the input record.
Better read the manual and post your queries. Click the below link for the manual.
