The above answer is do it with the JCL, if you want to do
the same with COBOL, you should be having two files, one is
input and the other one with new output file. Otherwise i
suppose we can't do it.

Fine I would like go with answer #2, since physical deletion
is not possible with ps datasets , all you can do is exclude
the records meeting the condition while writing it to new ps
datasets.
let me remind once again that Deletion is not possible with
ps data sets.

take the infile and outfile same in the jcl but in 2 dd
statement. Declare one ainput file to read and other as
output file to write in cobol program. Then read the file
and srore the file contents in an array/table. after
reading the full file write the file from the array records.

If you open the dataset in io mode can't we delete the
record, i think we can.
If it is a flat file or vsam file i think we can delete the
record but the space being used for that will not be recovered.
Please check it.

Answer / manikandan
Ofcourse you can do it. You can do it by a simple sort.
You can use either INCLUDE COND or EXCLUDE COND in the
sysin part.
Ex: If you want to delete a record whose first 4 characters
are 'BBBB', you can do it with the following sysin card,
SORT FIELDS=COPY
INCLUDE COND=(1,4,CH,NE'BBBB')
OR
SORT FIELDS=COPY
EXCLUDE COND=(1,4,CH,EQ'BBBB')
