SORT JCL to filter data using INREC or OUTREC

INREC can be used to filter or reformat the input data so that the sorting is more efficient.

In the following sort card the inrec statement will take the data from 7th pos (3 bytes) and put at positions 1st(3bytes) in the

output file and take data from 56th position (4 bytes) and put at position 4th (4bytes). The soting will occur on the first 3 bytes

of the output record.

INREC FIELDS=(1:7,3,4:56,4)

SORT FIELDS=(1,3,CH,A)

Example JCL is provided below.
