I have a KSDS file. I need to delete only specific records from that file say
if the date field in the file is 25 then only those records must be deleted.

You can use a DFSORT/ICETOOL job like the following. We process the VSAM file as variable-length (V). I've assumed that the 2-character field you want to check for is in positions 11-12, so the starting position for the OMIT statement is 15 (11 + 4 for the RDW).

Code:

//S1   EXEC  PGM=ICETOOL
//TOOLMSG   DD  SYSOUT=*
//DFSMSG    DD  SYSOUT=*
//VSAMFILE DD DSN=...  VSAM file
//T1 DD DSN=&&T1,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(,PASS)
//TOOLIN DD *
COPY FROM(VSAMFILE) TO(T1) VSAMTYPE(V) USING(CTL1)
COPY FROM(T1) TO(VSAMFILE) VSAMTYPE(V)
/*
//CTL1CNTL DD *
  OMIT COND=(15,2,CH,EQ,C'25')
/*
