HI All,

I want to find the MAX, MIN and AVG of a column. The file structure is given below

Code:
20110922ATQ0034
20101010WAT0001
20110203SQA0003
20110921ATQ0001
20110323WAT0022


MAximum should be found for column 12-15

Output should be like

MAX of Record Type ATQ is:0034
MIN of Record Type ATQ is:0001
----------
------
same for the others.

You can use a DFSORT job like the following to do what you asked for:

Code:

//S1 EXEC PGM=SORT                                         
//SYSOUT DD SYSOUT=*                                       
//SORTIN DD *                                               
20110922ATQ0034                                             
20101010WAT0001                                             
20110203SQA0003                                             
20110921ATQ0001                                             
20110323WAT0022                                             
//SORTOUT DD SYSOUT=*                                       
//SYSIN DD *                                               
  SORT FIELDS=(9,3,CH,A)                                   
  OUTFIL REMOVECC,NODETAIL,                                 
    SECTIONS=(9,3,                                         
      TRAILER3=('MAX of record type ',9,3,' is: ',         
        MAX=(12,4,ZD,TO=ZD),/,                             
      'MIN of record type ',9,3,' is: ',                   
        MIN=(12,4,ZD,TO=ZD),/,                             
      'AVG of record type ',9,3,' is: ',                   
        AVG=(12,4,ZD,TO=ZD),/,10'-'))
