title: SORT to replace a column in JCL
body: <p>Do you know a command to sort a file to replace a column with the same value in all the rows?</p>
  
  <p>For example, I want to generate a new file with the same order as the original, except at the column 66 to 68, I want to put XX in all the rows.</p>
  
  <p>Note: the row may have BINARY characters in some columns.</p>
