I have a file with LRECL=80,RECFM=FB with multiple fields. I need to filter out the records which have 4 consecutive alphabets ( in general , n consecutive alphabets ) in the position of 1 to 25.

Please suggest me how to achieve using sort card

This can be achieved using Fileaid. Check the following code. I have included conditions only to check for 'ABCD', 'BCDE', 'CDEF' & 'DEFG' for this example. You can include the next set of consecutive letters for your requirement.

Code:
//STEP01  EXEC PGM=FILEAID                             
//SYSPRINT DD SYSOUT=*                                 
//SYSLIST  DD SYSOUT=*                                 
//DD01     DD *                                       
ABCDKSDFJSLDJFS JJ                                     
GHLKHKCDEF                                             
DEA LKJLKJL                                           
/*                                                     
//DD01O    DD SYSOUT=*                                 
//SYSIN    DD *                                       
$$DD01 COPY IF=(1,25,C'ABCD',C'BCDE',C'CDEF',C'DEFG') 
/*                                                     



This will output the following records as o/p.

Code:
ABCDKSDFJSLDJFS JJ                                     
GHLKHKCDEF


Let me if it works.

Thanks,
Ram

nbdtrjk1,

The following JCL will give you the desired results.


Code:

//STEP0100 EXEC PGM=SORT           
//SYSOUT   DD SYSOUT=*             
//SYMNAMES DD *                     
ALP,C'ABCDEFGHIJKLMNOPQRSTUVWXYZ'   
//SORTIN   DD DSN=your input 80 bytes,DISP=SHR
//SORTOUT  DD SYSOUT=*                                             
//SYSIN    DD *                                                   
  SORT FIELDS=COPY                                                 
  INCLUDE FORMAT=SS,                                               
  COND=((11,1,EQ,ALP,&,12,1,EQ,ALP,&,13,1,EQ,ALP,&,14,1,EQ,ALP),OR,
        (12,1,EQ,ALP,&,13,1,EQ,ALP,&,14,1,EQ,ALP,&,15,1,EQ,ALP),OR,
        (13,1,EQ,ALP,&,14,1,EQ,ALP,&,15,1,EQ,ALP,&,16,1,EQ,ALP),OR,
        (14,1,EQ,ALP,&,15,1,EQ,ALP,&,16,1,EQ,ALP,&,17,1,EQ,ALP),OR,
        (15,1,EQ,ALP,&,16,1,EQ,ALP,&,17,1,EQ,ALP,&,18,1,EQ,ALP),OR,
        (16,1,EQ,ALP,&,17,1,EQ,ALP,&,18,1,EQ,ALP,&,19,1,EQ,ALP),OR,
        (17,1,EQ,ALP,&,18,1,EQ,ALP,&,19,1,EQ,ALP,&,20,1,EQ,ALP),OR,
        (18,1,EQ,ALP,&,19,1,EQ,ALP,&,20,1,EQ,ALP,&,21,1,EQ,ALP),OR,
        (19,1,EQ,ALP,&,20,1,EQ,ALP,&,21,1,EQ,ALP,&,22,1,EQ,ALP),OR,
        (20,1,EQ,ALP,&,21,1,EQ,ALP,&,22,1,EQ,ALP,&,23,1,EQ,ALP),OR,
        (21,1,EQ,ALP,&,22,1,EQ,ALP,&,23,1,EQ,ALP,&,24,1,EQ,ALP),OR,
        (22,1,EQ,ALP,&,23,1,EQ,ALP,&,24,1,EQ,ALP,&,25,1,EQ,ALP))
