SORT – JUSTIFY, SQUEEZE and OVERLAY
-
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’>’))
| JFY | is used to justify the input record |
| SHIFT=LEFT | tells that records needs to be shifted to left (SHIFT=RIGHT for right shift) |
| PREBLANK=C'()/’ | tells that the characters ‘(‘, ‘)’ and ‘/’ need to be replaced by blank. |
| LEAD=C'<‘ | tells that all records should be appended with ‘<‘ at start |
| TRAIL=C’>’ | tells that all records should be appended with ‘>’ at end |
-
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’}’))
| SQZ | is used to squeeze the input record |
| SHIFT=LEFT | tells that records needs to be shifted to left (SHIFT=RIGHT for right shift) |
| PREBLANK=C'()/’ | tells that the characters ‘(‘, ‘)’ and ‘/’ need to be replaced by blank. |
| LEAD=C'<‘ | tells that all records should be appended with ‘<‘ at start |
| TRAIL=C’>’ | tells that all records should be appended with ‘>’ at end |
| MID=C’.’ | MID=string specifies the string to replace removed blanks |
| PAIR=QUOTE | “ignore” blanks and PREBLANK characters between pairs of quotes |
| PAIR=APOST | “ignore” blanks and PREBLANK characters between pairs of apostrophes |
-
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.
