ADD SEQUENCE NUMBER

SORT FIELDS=COPY
OUTREC FIELDS = (1,80,SEQNUM,ZD,A)

NOW SORT SEQ NUM IN DESCENDING ORDER
SORT FIELDS=(81,4,ZD,D)

INCLUDE ONLY 2ND LAST REC
SORT FILEDS = COPY
INCLUDE COND = (81,4,ZD,EQ,0002')

REMOVE SEQ NUM FROM FILE & THIS REC IS SELECTED

Answer / abhijit

Suppose file has 100 Record

1,2,3.........................100

a) Read the file and Count the number of records into a variable
Suppose CNT_VAR = 100

b) Suppose you want to read 2nd record from Last

So Set N = 2

c) Now to find the search variable compute the below

SRC_VAR = CNT_VAR - N i.e (100 - 2)

SRC_VAR = 98

d) Now Read the file to pick 98th record from top
