The file which we are using is VSAm file then we can go for Key mentioned ,
If it is a sequential file we have to read till the 49th record then needs to delete the 50th record, this is the main disadvantage with Sequential files.

You can use SORT: copy first 49 record to a file

SORT FIELDS=COPY,STOPAFT=49

then copy the rest of the records starting from 51 to another file

SORT FIELDS=COPY,SKIPREC=50

then concatinate them to output file.

Why all of discussing as it's not possible. In VSAM we also having KSDS file. In that everyfile stored in Sequence numbers i mean Primary key values. First we have to move 50 to key number and apply delete syntax........... Simple

In case of PS files, we can convert the contents of the files into Table and then we can access them randomly and we can do our deletion also by going to the required occurence.

It is NOT possible to delete records of a seq file. If you do not want a specific record to be kept in a seq file any more, all you can do is to modify the contents of the record so that it contains some special values that your program will recognize as deleted (remember to open the file in I-O mode and REWRITE a new record).

In normal dasds the data cant be deleted where we like
for that ksds vsam files are used there we have option of index and randomly picking of data we want.So by file handling we can delete the 50th record and whatever the record we want to delete.
Hope Im right to some extent.Correct me if i am wrong...
