Hsubra,

The best way to solve the problem is to go step by step and not directly answer the request.

I have corrected minor mistakes in the counts in the examples.
Here is an other cntl statments that could be faster. I've removed some HIT=NEXT.
Code:

//ICE0CNTL DD *
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,5,ZD)),
        IFTHEN=(WHEN=(1,3,CH,NE,C'END'),
                OVERLAY=(86:SEQNUM,5,ZD,START=0,INCR=1),
                HIT=NEXT),
        IFTHEN=(WHEN=(1,5,CH,NE,C'START'),
                OVERLAY=(91:SEQNUM,5,ZD,START=1,INCR=1),
                HIT=NEXT),
        IFTHEN=(WHEN=(1,5,CH,EQ,C'START'),
                OVERLAY=(81:81,5,ZD,SUB,86,5,ZD,M11,LENGTH=5)),
        IFTHEN=(WHEN=(1,3,CH,EQ,C'END'),
                OVERLAY=(81:81,5,ZD,SUB,91,5,ZD,M11,LENGTH=5)),
        IFTHEN=(WHEN=(86,5,ZD,EQ,91,5,ZD),
                OVERLAY=(81:81,5,ZD,SUB,86,5,ZD,M11,LENGTH=5)),
        IFTHEN=(WHEN=(86,5,ZD,NE,91,5,ZD),
                OVERLAY=(81:C'00000'))
  OUTFIL FNAMES=OUTX,
         OMIT=(81,5,CH,EQ,C'00000'),
         OUTREC=(1,80)

Still thinking of it, my previous post can be modified a bit for a probable faster execution : assuming that doing a sub arithmetic is slower than a direct SEQNUM. The fact is I don't have a file big enough to test this.
Sorry for that.
Code:

//ICE0CNTL DD *
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,5,ZD)),
        IFTHEN=(WHEN=(1,3,CH,NE,C'END'),
                OVERLAY=(86:SEQNUM,5,ZD,START=0,INCR=1),
                HIT=NEXT),
        IFTHEN=(WHEN=(1,5,CH,NE,C'START'),
                OVERLAY=(91:SEQNUM,5,ZD,START=1,INCR=1),
                HIT=NEXT),
        IFTHEN=(WHEN=(1,5,CH,EQ,C'START'),
                OVERLAY=(81:SEQNUM,5,ZD,START=1,INCR=1)), <- HERE
        IFTHEN=(WHEN=(1,3,CH,EQ,C'END'),
                OVERLAY=(81:SEQNUM,5,ZD,START=1,INCR=1)), <- HERE
        IFTHEN=(WHEN=(86,5,ZD,EQ,91,5,ZD),
                OVERLAY=(81:81,5,ZD,SUB,86,5,ZD,M11,LENGTH=5)),
        IFTHEN=(WHEN=(86,5,ZD,NE,91,5,ZD),
                OVERLAY=(81:C'00000'))
  OUTFIL FNAMES=OUTX,
         OMIT=(81,5,CH,EQ,C'00000'),
         OUTREC=(1,80)

Once more...
My previous post shows how to remove unwanted records AND the possibility to be able to use a key group, unique between the groups for a SPLICE, later, for example. It means multi passes.
Here is a simplified way from a COPY, to only remove unwanted records with no further passes.
Code:

1       0000100001
START   00002     
A       0000300002
END          00003
1       0000400004
2       0000500005
START   00006     
A       0000700006
B       0000800007
END          00008
1       0000900009
2       0001000010
3       0001100011
START   00012     
A       0001300012
B       0001400013
C       0001500014
END          00015
1       0001600016

Code:

//ICE0CNTL DD *                                         
  INREC  IFTHEN=(WHEN=(1,3,CH,NE,C'END'),               
                 OVERLAY=(81:SEQNUM,5,ZD,START=1,INCR=1),
                 HIT=NEXT),                             
         IFTHEN=(WHEN=(1,5,CH,NE,C'START'),             
                 OVERLAY=(86:SEQNUM,5,ZD,START=1,INCR=1))
  OUTFIL FNAMES=OUTX,                                   
         OMIT=(81,5,ZD,EQ,86,5,ZD),                     
         OUTREC=(1,80)                                   
/*

Hoping all of that is still clear

The last post gave me the idea to improve the one I posted before the last by removing one IFTHEN.
The logic changes a bit : the synchronisation between ColC & ColD means that the records to remove;
the desynchronisation, the records to keep.
The group key is ColB.
Code:

ColA    ColB  ColC  ColD
A       00001 00001 00001
START   00001 00002     
A       00001 00003 00002
END     00001       00003
A       00005 00004 00004
A       00006 00005 00005
START   00002 00006     
A       00002 00007 00006
B       00002 00008 00007
END     00002       00008
A       00011 00009 00009
A       00012 00010 00010
A       00013 00011 00011
START   00003 00012     
A       00003 00013 00012
B       00003 00014 00013
C       00003 00015 00014
END     00003       00015
A       00019 00016 00016

Code:

//ICE0CNTL DD *                                               
  INREC  IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,5,ZD)),         
         IFTHEN=(WHEN=(1,3,CH,NE,C'END'),                     
                 OVERLAY=(86:SEQNUM,5,ZD,START=1,INCR=1),     
                 HIT=NEXT),                                   
         IFTHEN=(WHEN=(1,5,CH,NE,C'START'),                   
                 OVERLAY=(91:SEQNUM,5,ZD,START=1,INCR=1),     
                 HIT=NEXT),                                   
         IFTHEN=(WHEN=(1,5,CH,EQ,C'START'),                   
                 OVERLAY=(81:SEQNUM,5,ZD,START=1,INCR=1)),     
         IFTHEN=(WHEN=(1,3,CH,EQ,C'END'),                     
                 OVERLAY=(81:SEQNUM,5,ZD,START=1,INCR=1)),     
         IFTHEN=(WHEN=(86,5,ZD,NE,91,5,ZD),                   
                 OVERLAY=(81:81,5,ZD,SUB,91,5,ZD,M11,LENGTH=5))
  OUTFIL FNAMES=OUTX,                                         
         OMIT=(86,5,ZD,EQ,91,5,ZD),                           
         OUTREC=(1,80)

I hadn't tried how dfsort would react if I substracted a num value to a blank (for HDR & TRL). Well, a blank is treated as a zero and that's mean that the last IFTHEN from the last post could be removed and the OMIT changed to an INCLUDE.
Code:

//ICE0CNTL DD *
  INREC  IFTHEN=(WHEN=INIT,
                 OVERLAY=(81:SEQNUM,5,ZD)),
         IFTHEN=(WHEN=(1,3,CH,NE,C'HDR'),
                 OVERLAY=(86:SEQNUM,5,ZD),
                 HIT=NEXT),
         IFTHEN=(WHEN=(1,3,CH,NE,C'TRL'),
                 OVERLAY=(91:SEQNUM,5,ZD),
                 HIT=NEXT),
         IFTHEN=(WHEN=(1,3,CH,EQ,C'HDR'),
                 OVERLAY=(81:SEQNUM,5,ZD)),
         IFTHEN=(WHEN=(1,3,CH,EQ,C'TRL'),
                 OVERLAY=(81:SEQNUM,5,ZD))
  OUTFIL FNAMES=OUTX,
         INCLUDE=(86,5,ZD,NE,91,5,ZD),
                  OVERLAY=(81:81,5,ZD,SUB,86,5,ZD,M11,LENGTH=5)

Blanks are treated as zero for ZD because the X'40' is treated as a zone of 4 (ignored) in all but the last byte, a sign of 4 (positive) in the last byte, and a digit of 0 in all bytes.

The previous post gives a good result but the group key is invalid.
Here is the correction.
Code:

//ICE0CNTL DD *                                           
  INREC  IFTHEN=(WHEN=INIT,                               
                 OVERLAY=(81:SEQNUM,5,ZD)),               
         IFTHEN=(WHEN=(1,3,CH,NE,C'HDR'),                 
                 OVERLAY=(86:SEQNUM,5,ZD),               
                 HIT=NEXT),                               
         IFTHEN=(WHEN=(1,3,CH,NE,C'TRL'),                 
                 OVERLAY=(91:SEQNUM,5,ZD),               
                 HIT=NEXT),                               
         IFTHEN=(WHEN=(1,3,CH,EQ,C'HDR'),                 
                 OVERLAY=(81:SEQNUM,5,ZD,5X'F0',5X'40')),
         IFTHEN=(WHEN=(1,3,CH,EQ,C'TRL'),                 
                 OVERLAY=(81:SEQNUM,5,ZD,86:5X'F0'))     
  OUTFIL FNAMES=OUTX,                                     
         INCLUDE=(86,5,CH,NE,91,5,CH),                   
         BUILD=(1,80,81:81,5,ZD,SUB,86,5,ZD,M11,LENGTH=5)
/*

Sorry for that.
