Hi All,

I need to increment the counter ( Pos :131 - line 5) based on value present in Line 8. example below


I need to match the value from line 16 and compare it with value in line 8. If the values match , I need to increment the counter in line ( 16 - 3 = 13).. So on

File is FB and LRECL is 150



Code:

martin,

The following DFSORT/ICETOOL JCl will give you the desired results. I assumed that the value you need to check is in pos 1 for 5 bytes and the seqnum field to be populated is 8 bytes in pos 131.

Code:

//STEP0100 EXEC PGM=ICETOOL     
//TOOLMSG  DD SYSOUT=*         
//DFSMSG   DD SYSOUT=*         
//IN       DD DSN=your 150 byte FB file,DISP=SHR
//T1       DD DSN=&&T1,DISP=(,PASS),SPACE=(CYL,(X,Y),RLSE)     
//OUT      DD SYSOUT=*                                         
//TOOLIN   DD *                                               
  COPY FROM(IN) USING(CTL1)                                   
  SORT FROM(T1) USING(CTL2)                                   
//CTL1CNTL DD *                                               
  INREC IFTHEN=(WHEN=INIT,                                     
  OVERLAY=(151:SEQNUM,8,ZD,SEQNUM,3,ZD,START=125,INCR=125,5X)),
  IFTHEN=(WHEN=(159,3,ZD,EQ,0),                               
  OVERLAY=(162:1,5,167:SEQNUM,8,ZD,RESTART=(159,8))),         
  IFTHEN=(WHEN=(159,3,ZD,GT,0),OVERLAY=(159:8C'0'))
           
  OUTFIL FNAMES=T1,IFOUTLEN=167,                               
  IFTHEN=(WHEN=(167,1,CH,GT,C' '),                             
  BUILD=(150X,151,8,ZD,SUB,+3,M11,LENGTH=8,167,8,/,1,159))     
//CTL2CNTL DD *                                               
  SORT FIELDS=(151,8,CH,A),EQUALS                             
  SUM FIELDS=(159,8,ZD)                                       
  OUTFIL FNAMES=OUT,IFOUTLEN=150,                             
  IFTHEN=(WHEN=(159,8,ZD,GT,0),OVERLAY=(131:159,8))
