我有一个包含4个不同部门的已处理信息的数据集,我需要将其拆分为每个部门的一个数据集。这是一般记录结构:

XXXXXXX =无关字符串

AAA = 3个字母的alpha部门ID

记录详细信息无关紧要,行数可变

000001 0000000000000000000000000000000000000XXXXXXXAAA171220150000              
000002 <irrelevant record details>
000003 <irrelevant record details>
000004 999999999999999999999999999999999999900000004000000000005700     
000005 0000000000000000000000000000000000000XXXXXXXBBB171220150000              
000006 <irrelevant record details>

000008 <irrelevant record details>

000012 0000000000000000000000000000000000000XXXXXXXCCC171220150000

如何使用DFSORT和JCL完成此操作?

以下是使用INREC WHEN = GROUP的解决方案的示例代码,用于2个部门:

//SRT0001    EXEC PGM=SORT
//SYSOUT     DD SYSOUT=*
//SORTIN     DD DSN=DATASET.IN,
//           DISP=SHR
//AAAOUT     DD DSN=DATASET.OUT.DEPAAA,
//           DISP=(,CATLG),AVGREC=U,SPACE=(150,(100,10),RLSE)
//BBBOUT     DD DSN=DATASET.OUT.DEPBBB,
//           DISP=(,CATLG),AVGREC=U,SPACE=(150,(100,10),RLSE)
//SYSIN      DD   *
 SORT FIELDS=COPY
   INREC IFTHEN=(WHEN=GROUP,
     BEGIN=(1,4,CH,EQ,C'0000'),
     END=(1,4,CH,EQ,C'9999'),
     PUSH=(151:45,3))
   OUTFIL FNAMES=AAAOUT,
     INCLUDE=(151,3,CH,EQ,C'AAA'),BUILD=(1,150)
   OUTFIL FNAMES=BBBOUT,
     INCLUDE=(151,3,CH,EQ,C'BBB'),BUILD=(1,150)
