I have number of records in my file... But I don't know how many records there are... In such a situation how can I access the last record directly..? Is it possible to read the last one without reading the previous ones...

Code:

Sort products are not able to read records backwards so they cannot read the last one without reading the previous ones.

Hi there,

Code:

  INREC FIELDS=(1,80,SEQNUM,8,ZD)     
  SORT FIELDS=(81,8,ZD,D)             
  OUTFIL ENDREC=1,OUTREC=(1,80)


Hope this will helpful

Ekta,

Although that method does get the last record, it does NOT do what was asked for which is to read the last record without reading the previous ones. It does, in fact, read ALL of the records to get to the last one.
