If you cannot fit your SORT statement (or any other DFSORT control statement) between columns 2 through 71, you can continue it on the next line. If you end a line with a comma followed by a blank, DFSORT treats the next line as a continuation. The continuation can begin anywhere between columns 2 through 71.

For example:

 SORT FORMAT=CH,FIELDS=(110,10,A,145,17,A,
    1,75,A)
