SORT – JUSTIFY, SQUEEZE and OVERLAY

 

1. JUSTIFY
   

   Using SORT, you can justify your input records.
   

Suppose you have your input file as below:

(RAJESH/

RAMS/

SUNIL/

SURESH)

And you want your output file in this format

<RAJESH>

<RAMS>

<SUNIL>

<SURESH>

Your SORT card would look like below:

OPTION COPY

OUTREC FIELDS=(1,20,JFY=(SHIFT=LEFT,PREBLANK=C'()/’,

LEAD=C'<‘,TRAIL=C’>’))

1. SQUEEZE
   

   Using SORT, you can SQUEEZE your input records. That is you can remove unwanted spaces in between in a record.
   

Suppose you have your input file as below:

A (RAJESH/ A

B RAMS/ B

C SUNIL/ C

D SURESH) D

“E CHIRU ” E

And you want your output file in this format

{A.RAJESH.A}

{B.RAMS.B}

{C.SUNIL.C}

{D.SURESH.D}

Your SORT card would look like below:

OPTION COPY

OUTREC FIELDS=(1,20,SQZ=(SHIFT=LEFT,PREBLANK=C'()/’,MID=C’.’,

LEAD=C'{‘,TRAIL=C’}’))

1. OVERLAY
   

   The OVERLAY parameter of the OUTREC statement can be used if you only want to change one or a few items and keep the rest of the record in its original form
   

   Suppose you want to change the data present in bytes 6 to 10 to upper case and leave the other part of the data as it is, you can use below OVERLAY.
   

   OPTION COPY
   

   OUTREC OVERLAY=(6:6,5,TRAN=LTOU)
   

 

This will copy the data from bytes 1 to 5 as it is into the output file and convert the chars present in bytes 6 – 10 into upper case.
